It's working. I had the image sizes set wrong and when I looked at the
source code, all I saw was the script, not the result of the script. I
expected only the desired <img> tag to be there. I thought it wasn't
working. For anyone trying anything similar, it helps to specify a temporary
border around your invisible image in order to see what is going on.
I was hoping there was a Java way to pull in the screen dimensions, but I
guess you get what you get sometimes.
Thanks for your help, and your patience...
Chris
