Topic: showImage() [REVISED]

I've revised my question, as I think I can get this to work if I can figure out 1 thing:

what function is called 1) after the image is loaded AND 2)  currently selected?  i have animation I want to play after this happens when the image is revealed, and I can't figure it out.

I've been working exclusively in
Image.showImage() was my guess, but gets executed twice - once when the image is selected, then again once the image is loaded.
