Fatal error: Allowed memory size - can't upload HQ pictures

[Katya]

Hello! I read some topics in this forum but still can't understand how i can fix my problem
I upload some HQ files in FTP, but i can't added them in the gallery - i have this problem:

Fatal error: Allowed memory size of 16777216 bytes exhausted (tried to allocate 6004 bytes) in /usr/home/vshosts/hosts/www/gallery/include/picmgmt.inc.php on line 262

I open picmgmt.inc.php file but i don't know what i need to edit to upload my HQ pictures

Then alternative 1 doesn't apply for you, but only the alternatives 2 and 3 that Nibbler has refered to already
