Uploading images using PHP and script memory limit

Question

I am trying to load a JPG image using a PHP script, but the image continues to force my script to time out and die, giving this error:

Fatal error: Allowed memory size of 33554432 bytes exhausted (tried to allocate 
2136 bytes) in image.php on line 38

How can I prevent the download if the image is too large, or this error failed?

Answer 6

Does this happen with all download attempts regardless of file size? I only encountered such a problem when there was a script error - usually this is a loop that got out of hand.
