How to make 3 different sized images to scale evenly across a page or canvas in Gimp or Adobe

I took these three images and created the layers and display them in the images below. For some reason I scaled them and they seem to be synchronized together. When I select one layer all of the layers resize together on the canvas. I am a bit confused as to how this happened. In a related question yesterday, I picked an image that shows three simpler images together displaying virtually what I wanted. I was not looking to place them in that image just figure out how to make them more uniformly sized to fit better on a web page that will look similar. The answer given yesterday was fantastic.

So my question:
How do I break out the three images now into separate files like a thumbnail and save them individually so that I can place them on my web page? Thank you very much for your expertise.

I see you still need a bit of help with scaling. See if this helps:ScaleNotice that there is an 'Eye' icon on each layer (left-hand side)

this allows you to hide/unhide a layer

to save each image individually, click on the eye to hide all but one layer and use 'Export as' to create a file for the visible layer

do this for each individual image - to get rid of the extra space, you can crop each image by opening the individual files afterwards

if this is not clear, please let me know

Aren't we all and when are they going to realize that. It's like it is nice to go to dinner at a 5 star but unfortunately, most of us can only afford to go home and cook what we got....! At some point these giants will have to relent to the quality that GIMP brings to the picture and the ease of use. Adobe should make their products more reasonable. I will not be upgrading anytime soon that is for sure.
