Users get this error message when they try to upload a photo
Fatal error: Allowed memory size of 16777216 bytes exhausted (tried to allocate 800 bytes) in /data/13/1/129/135/1292787/user/1383692/htdocs/forums/photopost/image-inc.php on line 139
You can increase your PHP memory in your php.ini file or put a memory override ini_set line in our of our files to raise memory if it becomes an issue.
That error comes from your server because your image processor is choking on the file and using all php's memory. This will help. Upgrading is always good but will not specifically solve this issue.
