I have been using an upload script that has been working fine, but now it seems I am getting an error on almost all the files I upload. The script accually makes 3 images, thumbnail, midsized and orginal and uploads all. The error is as follows:

Fatal error: Allowed memory size of 8388608 bytes exhausted (tried to allocate 5236 bytes) in /var/www/html/product-add-pictures-function.php on line 52

I understand that that 8mb and the files Im uploading are only around 500-800 KB.

Are there some tips that I can free up some PHP RAM on my server? I think 8mb is the max Im allowed. Could it be the way Im uploading the file, below is the upload script:

<?php 
//	upload_function.php
//
//	this page contains the upload function for upload_picture.php it also
//  dynamically creates the filenames and store the picture in the /pictures/ dir

    is this the product-add-pictures-function.php page?

      yes it is, a temporary fix is that we limited the files to under 300kb, but i am interested if there is anything we can do to help free up some ram.

      thanks for the interest

        The reason that your memory is being exausted is bceause images are stored in the disk in compressed format and take up much more when they are read in through the GD library. Compiling your PHP engine with out the --enable-memory-limit option is one choice and editing php.ini to increase the memory limit is another.
