Hmm, It wasn't really on my list... I was hoping to get most of the "guts" of the image viewing working first (including smoother panning as requested above, and zooming if possible) and then releasing the source for someone else to work on... Someone around here did a "viewer" app which is a text file viewer that allows you to walk your filesystem and view text files, I figure someone out here can use that program's source and mine to come up with something like you're describing.
But if my other Empeg projects become too frustrating, I'll see what I can do. This one is a lot easier to work on, and a nice break from when I'm way above my head trying to get text-to-speech to work.
