How to Add and Print Excel Background Images

You can enhance the appearance of your Excel spreadsheet and make it more visually attractive to an audience. The best way to spice it up is to add an Excel background image. This article will show you several different ways to do so.  

You can use an image as a background or a solid color or pattern. There are basically three ways you can do this in Excel: using Page Layout, adjusting the transparency of an image and inserting an object.

Add an Excel Background Image In Excel Using Page Layout

  • Open the page layout ribbon by clicking on Page Layout
  • Look under the Page Setup section for Background.
  • Click on Background and see the three options – from a file, Bing Image Search, and OneDrive-Personal.
  • Let’s start by selecting the first option From a file and choose an image from your computer.
  • Select an image and then click Insert. See the background chosen behind your data in the screenshot below.

As you scroll down the page or as you move from side to side, the image repeats itself over and over in the background.

Be careful with the Excel background image you choose to use. As you can see in the image above, the data is obscured in many areas because the area on the picture is dark and so is the text.

You have a few options. You can change the color of the text and bold it.

Keep in mind that your data is the focal point of your spreadsheet. If the Excel background image makes it hard to read, you are diluting the impact of your information.

This is a downside of using background images. You don’t want the background to interfere with your data. 

Another disadvantage is the data gets smaller when you zoom out on your spreadsheet while the image size stays relatively the same.  

If you zoom in, the text gets larger, and the image remains relatively stable.

The Excel background image does not follow the data by staying proportional to it. Let’s use the second option now to add a background.

First, delete the old one by going to Page Layout > Delete Background.

The second option is to insert a picture from a Bing Image Search. This is often a better option because you might not have the best image on your computer.

Since this spreadsheet is about financial information in different countries, let’s search for images about maps

By default, the search will only bring up results for Creative Commons images. These are images that have been uploaded to the web to be shared.

Click on the filter icon to only see the image Sizes, Types, Layouts, and Colors and select the ones you prefer.

See the screenshot below with a picture of a map background. I bolded the black text to make it stand out more.

Backgrounds can be visually appealing, but you must be careful that they don’t make your text unreadable.

When you insert an Excel background image using this method, the image does not show up when printed. 

It is therefore only useful when you are showing your spreadsheet to others in a presentation and you want to grab their attention.

Insert a Picture & Adjust Its Transparency

Make sure you are on the Home tab and go to Insert > Pictures.

Choose an image from your computer and click Insert. Notice that the picture is not a background image. It is floating on top of the spreadsheet data.

You can move the image around the spreadsheet and resize it by putting your cursor on one of the circles on the edges and dragging it.

An advantage of inserting an Excel background image rather than adding a background is that you can adjust the transparency. If your spreadsheet is very long, this method might not be the most convenient method.  

Start by pushing the image to the top left-hand corner of your spreadsheet. Then drag the picture so that it covers all the data.

Adjust the transparency by clicking on the image. Then click on Picture Format tab > Transparency > Picture Transparency Options.

Add transparency to the picture so that it is sitting in the background and the data is behind the data. Move the toggle on the Transparency option to the right until the data becomes clear and can be easily read. 

This method uses an inserted picture that behaves like a background image and will show up when printed.

Insert An Object In Excel

If your spreadsheet is very long, the previous method could be cumbersome. Inserting an object might be a better option.

  • Start by clicking Insert from the ribbon menu. 
  • Then click Shapes. The drop-down menu next to Shapes will open. 
  • Select a shape by clicking on it. We will use a rectangular shape. Using your mouse, drop the shape on your spreadsheet to create it.  
  • Then resize it by dragging the circular buttons around the shape until it covers all your data. Right-click on the shape and select Format Shape.
  • Click Fill from the menu > Picture or texture fill > Insert (under Picture source). Insert a picture from a file, online pictures, or from icons.
  • Let’s choose a Texture fill. Under the Format Shape, select Picture or texture fill. Then click the drop-down menu next to Texture and choose one to use.
  • The texture will fill the shape and cover your data. Use the slider next to Transparency to set a percentage that allows your data behind the texture to show. In the screenshot below, we used 75% transparency.

When you use this method, the background will show up when you print.

When adding a background to an Excel spreadsheet, keep in mind that being able to read your data clearly is vital.

Adjusting the transparency of the background and changing the font color or style can improve the readability of your data while adding a little pizzazz to your spreadsheet.

Installing GIMP Plugins: A How-To Guide

GIMP (GNU Image Manipulation Program) is a free and open-source photo-editing program used by many as an alternative to Photoshop. It’s great for a range of design tasks including restoring old photos and creating custom thumbnails.

Some of its most powerful assets are the plugins developed by independent programmers. Plugins are small pieces of software that improve GIMP’s functionality and add new features to it.

Installing GIMP plugins starts with copying the plugin to the appropriate directory and then restarting GIMP.

Where Is Your GIMP Profile?

GIMP keeps the following user’s information in the GIMP profile (directory or folder):

  • Settings and presets for tools.
  • Keyboard shortcuts.
  • Brushes, palettes, gradients, scripts, plugins, brush dynamics, patterns, and fonts.

Users can find their GIMP profile in the following locations for various operating systems:

  • Linux: /home/{your_id}/.gimp-2.10.4 (or your version of GIMP)
  • OSX: /Users/{your_id}/Library/GIMP/2.10.4 (or your version of GIMP)
  • Windows: C:\Users\your-name\Appdata\Roaming\GIMP\2.10.4\ (or your version of GIMP)

When you restart your system, GIMP will scan your directories and load the plugins available. There are three types of GIMP plugins:

  • Script-fu extensions with a .scm extension.
  • Zip files.
  • Python scripts with a .py extension.

Where To Put Script-fu Extensions

  • From the Gimp top menu, go to Edit > Preferences > Folders > Scripts.
  • If you are using Windows and see more than one directory like in the screenshot above, choose your user or home directory.
  • Copy the .scm plugin to your directory. When you re-start GIMP, it will be in your plugin Script-Fu menu.

Where To Put Zip Files & Python Scripts

You will need to copy the files for these plugins to the GIMP plugins directory. Extract the zip files first and copy the contents, not the zip file.

Go to Edit > Preferences > Folders > Plugins to get to the plugins directory. In Windows, choose your user or home directory.

Copy the contents of the zip file and the .py file to the plugin’s directory, restart GIMP, and the plugins will be in your GIMP menu.

Installing GIMP Plugins Manually

  • If the plugin is in a zip file, extract the files and copy its contents to GIMP’s plugins and scripts folder. From GIMP, go to EditPreferences > Folders.
  • Scroll down to the Plug-ins and Scripts sections. You will see two folders in each section. The first is a system folder. The second is the user folder.
  • Click on the second folder.
  • Open the file manager by clicking on Show file location in the file manager.
  • Move PY formats into the Plug-ins folder
  • Move SCM formats into the Scripts folder.
  • Restart GIMP.

Installing GIMP Plugins Automatically

Some plugins included in the GIMP distribution come with their own installer. This varies with the operating system and the plugin itself.

Most of these plugins are accessed through the Filters menu. Double-click on the plugin to install it.

Keep in mind that GIMP Scripts and Plug-ins are platform-specific. Make sure when choosing files to download that they match your operating system.

Below are some popular plugins for GIMP.

BIMP – Batch Image Manipulation Plugin

BIMP enables users to apply manipulations to a group of images such as:

  • Change compression and format
  • Resize
  • Flip and rotate
  • Crop
  • Watermark
  • Change compression and format
  • Color and curve correction
  • Rename

Hugin

You can assemble a mosaic of images to create a panorama with Hugin.

Hugin is available for Linux, Windows, and Mac and functions as a standalone app.

Refocus

Some pictures come out blurry or out of focus. Refocus will try to fix them by smoothing the edges to clear up the photo.

Adjust the parameters in the plugin dialogue and preview your results.

CarTOONize

Convert your photos into cartoons with CarTOONize. Choose between five different filters.

Darktable

Darktable is a photography workflow application. It acts as a virtual lighttable and darkroom managing a database of your digital negatives.

View your negatives through a zoomable lighttable. Develop and enhance raw images.

Watermark

Unfortunately, people steal others’ content on the Internet and it’s challenging to prevent. However, you can protect your digital art by using the Watermark GIMP plugin.

Add a watermark text to your images to protect them. Choose from size, fonts, and position options. This plugin is a Script-Fu plugin.

Beautify

Improve and brighten your pictures with Beautify.

Aggregate many different editing options and photo effects into one interface. Use this plugin to turn GIMP into your very own photo retouching studio. Correct contrasts and colors, apply filters, and add a little glamour to your photos.

GIMP is a free and powerful photo editing tool. With the addition of plugins, GIMP is one of the best free alternatives to Photoshop.

How To Add Audio Narration To a Powerpoint Presentation

PowerPoint is an app that enables you to create and deliver an engaging presentation to an audience. But what if the audience is not in the same room or you are sending it as a link or attachment?

This is why adding audio narration to PowerPoint slides timings is helpful and useful. You can record the narration from inside your presentation so that it plays while viewers watch. Adding voice-over narration to your Powerpoint presentation or video will turn it into evergreen stand-alone content.

This article will discuss how to add audio narration to a Powerpoint presentation for Windows 10.

Test Your Default Microphone

The first thing you will need is a working microphone. Most computers today come with a built-in microphone. If you plan to use your computer default microphone, you don’t have to take additional steps to add a microphone.

However, you do want to make sure it’s working and loud enough to hear. To set your default microphone, test it to make sure it’s working. To customize the properties, follow the steps below.

  • Start by typing Settings in the search bar.
  • Click on System > Sound.
  • Look under Input for options to configure your microphone. Click the dropdown menu under Choose your input device to assign your default microphone.
  • If you only have one microphone, there is nothing to select. To open additional microphone settings, click on Device properties > Additional device settings.
  • Enable or disable speaker and access audio driver information under the General tab.
  • The Listen tab enables you to allow or deny your mic to listen to the speakers.
  • Adjust the microphone volume and balance settings under Levels.
  • Change the default sample rate and bit depth under the Advanced tab.
  • If enabled on your computer, Spatial sound can enhance the audio experience. 

To test your microphone, go back to the Input section. If it’s not working, you can use the Troubleshoot button to try to resolve the issue.

Install a USB Microphone

  • To enable your microphone, first, plug in the USB microphone to your computer. Then right-click on the volume icon on the taskbar. 
  • Click on Sounds.
  • Under the Recording tab, choose the microphone you want to set up and click Configure
  • Under Configure your Speech Recognition experience, click on Set up microphone.
  • When the setup wizard starts, choose the type of microphone you are installing and click Next.
  • The next screen you see will provide tips for using your microphone and some text to read to test your settings. 
  • Follow the instructions from the wizard and test the microphone to make sure it is working correctly.  

Set USB Microphone As Input Device To Use

If you want to use the external USB microphone you just set up to record your narration, you need to set it as the input device.

  • Right-click on the volume icon on the right side of the taskbar and click on Open Sound settings.  
  • From the Sound Settings window, scroll down to Input and tick the box under Choose your input device
  • Select your USB microphone as the input device.

Rehearse & Take Notes

Now that your microphone is set up and tested, instead of jumping right in and starting to record, take the time to practice what you are going to say.

Take notes, write out a script, and rehearse the timings to save time, minimize errors, and ensure that your audio sounds fluid and natural.

Now you are ready to start recording.

Turn On the Recording Tab (Office 365)

  • To turn on the Recording tab, navigate to File, click Options > Customize Ribbon > Recording > OK.

  • You will now have a visible audio icon on your slide. To hide this icon for your final presentation, click on it. 
  • Click Playback in the top bar navigation, and tick off Hide During Show.

Record An Audio Narration For An Entire Slideshow (Office 365)

  • Click on Recording from the top navigation, and then Record Slide Show
  • Choose either Record from Current Slide or Record from Beginning. The slideshow will open in the Recording window.
  • There are buttons on the top left for recording, pausing, stopping, and playing. Click on the red, round button to start recording. There will be a three-second countdown for you to get ready.
  • The slide you are recording will show up in the main pane of the window. To advance to the next slide, use the arrow on the right side of the window. To move to a previous slide, use the arrow on the left. Powerpoint with Office 365 will automatically record the time you spend talking on each slide. This includes any animations you have set up.
  • Use the buttons on the bottom right-hand side of the screen to toggle your microphone, camera, and camera preview on or off. If you choose to re-record part or all your narration, Powerpoint will erase the old version to enable you to record again.
  • When you finish recording, click on the square button at the top left-hand corner of the recording window.
  • The timings for each slide will show up in the Slide Sorter view. To see your timings, click on View > Slide Sorter.

  • You can also manually set your slide timings to sync with your narrations. To do so, select the slide from Normal View and then click on Transitions
  • From the Timing group, select the After check box under Advance Slide.
  • Enter how long you want the slide to stay on the screen before moving onto the next. Do this for every slide you want to use manual timings.

Publish Your Presentation For Sharing

You can save your presentation as a Powerpoint Show (.ppsx) or a video to share it with others. When a viewer opens a slideshow file, it will immediately open in slideshow mode.

To save your presentation, go to File, Save As and select the format from the dropdown menu.

If your presentation is huge and you want to send it as an email attachment, you might need to compress the file. A better option is to upload it to Dropbox, OneDrive, or Google Drive, and send the link to the desired recipients.
