Are you trying to crop the picture from within the pdf file, or do you want to load the image into a web page and crop from there?
The second thing you said...
Basically, I want them to see how the final piece (a postcard) is going to look, and then when they click the final submit, it sends a pdf to "me" somewhere that I can then print. So if we do it on the actual pdf, (not likely), or on a dynamically generated image/gif/??? then that's fine. It really is just to allow end usere who have no idea how to use Photoshop/image editing tools to make their photo look like they'd like it to.
I'm also going to need to test their upload to make sure it meets a baseline of size and dpi requirements. Is that easily doable? I'm going to do some in-depth study of php's image functions unless there's a better way?
