Hi John,

Yes, there is a way to select all images in your spreadsheet at once. Here's how:

1. Click on any image in your spreadsheet to select it.
2. Press "Ctrl" + "A" on your keyboard. This will select all objects in your spreadsheet, including images.
3. Now, you can resize all the images at once by going to the "Format Picture" tab and adjusting the size as needed.
