class.upload.php is a powerful and mature PHP class to manage uploaded files, and manipulate images in many ways. The script is available under a GPL license.
Check you webserver logs, it will tell you why the page crashes.
If you need to upload very large images, you'd better off using ImageMagick for instance; PHP/GD is not really appropriate for intensive processing.Reply
My source image is 4608 X 3072 and am processing it 4 times to 4 different sizes.
Even if I don't process the first time the remaining 3 don't work either.
Not really sure how to deal with this since images that will be uploaded by users are likely to be of large pixel size, i.e. from a digital camera.
Thanks, Dan
