I'd like to resize an image for display, and have the original linked to by the new temporary image. I'd like to make the new image have width="550" and have it's height be proportionate to this. I just checked my webhost and it has gd 2.0.15 installed. I found a thread which might help me, but I don't know how to apply the function to specific images rather than all images on a page. Could you point me in the right direction?
