I'm looking for a script that takes a picture, resizes it, and outputs it with a new filename. That or even better, a script that temporarily resizes an image to the desired size, without using the img tag to resize it, because if you do it that way the file size won't be reduced. The current script i have doesn't work with gif files, so that rules it out.
I'm also curios as to what method is the most practical or most used for image resizing on most websites where you can upload your own files. Is the most practical method creating a new picture resized, or using code to resize it everytime you display it somewhere? I'll probably be displaying it in 2-3 different sizes.
