Image Upload Problem (Previous Post Disappeared..)

[happypete]

took out all the '@'s on the resize class and get a new error:

 

Fatal error: Allowed memory size of 33554432 bytes exhausted (tried to allocate 10944 bytes) in /home/user/public_html/accounts/inc/resize-class.php on line 45

do i need to increase the limit on the resize_class.php, if so, any suggestions on how?

 

line 45: $img = imagecreatefromjpeg($file);
