Well, I'm no expert, but heres my idea.
You catch the window resize event using a Select WaitEvent or Select PeekEvent. The event id is $802.
Keep a Const value of the Base Window Width (BWW) and the Base Window Height (BWH). Then use ScaleImage for every image, with the X param as BWW/New Window Width, Y param as BWH / New Window Height.
Two extra suggestions: Have duplicates of the images, the base image that you load, and an image that you display. Whenever you scale the images, make the display image a scale of the base, so the image doesn't get too distorted.
Second: You may need to work out a formula for the images postition, as this may need to change as the window is resized.
I hope I've helped.
