exit();

I googled it for you, people should learn to use google

The GD image functions operate on an uncompressed bitmap version of the image (jpg, gif, png use data compression to reduce the file size) and require a relatively large amount of memory.

 

Each of your image resources $im, $newimage, and $thumb should be destroyed, see imagedestroy, immediately after you are finished with each of them in the loop so that the memory taken by them is available for the rest of the code and for the next iteration of the loop.

Oh yeah PFMaBiSmAd is so right. Didn't even look the code this time and just googled the error. I take back my comment about that people shud learn to google.
