[thelist] Web-Based Hidden Image Optimization

[Rob Smith]

:-\

I have a feature on one of my sites that allows the user to upload an image.
However, I would also like to limit the physical width's and heights to A)
100 x 100 (small thumbnail) B) 200 x 200 (large thumbnail) C) 600 x 450
(photo gallery)...

Sure I can force a ... width="200" in the image tag, but in some cases, the
images default width is smaller thereby pixilating the image. 

Are there any "plug-ins" for what I'm trying to accomplish. Open-source or
for purchase are ok. Anything on php is preferred.

Side bar history: Digital cameras are increasingly getting better, and the
users are growing less savvy about proper image editing for web placement. I
need to counter this some how.
