Alright, Benoit Hediard ([EMAIL PROTECTED]) was nice enough to give me additional details to his ImageJ solution. I asked for his permission in posting it and he's cool with it, figured some others might be interested. Your mileage may vary, use at your own risk, I'm not responsible - nor is Ben Hediard. ;) There's a lot more stuff in ImageJ, this is just one example (from what I'm told, you could also write one to transform a .gif file into a .jpg file, I would imagine this would come handy with those wanting to dynamically import .jpg's).
Cheers, ~Todd ------------------------------------------------------ Step 1.) Head over to http://rsb.info.nih.gov/ij/index.html and download ImageJ http://rsb.info.nih.gov/ij/download.html Step 2.) Put Download "ij.jar", put it in "WEB-INF/lib" Step 3.) Hiccup the server (restart it) Step 4.)
