[The Geek]

Cool. Found out what I think the problem is with some users not getting this to work.
I would lay money on the fact that those having problems store their avatars in the DB instead of the filesystem.

So, if thats the case... try this:
edit includes/functions_upload.php and after EACH (there are 2):

PHP Code:

$maxsize = &$imagepermissions[$type . 'maxsize']; 


add

PHP Code:

require_once('./includes/functions_geekautoavatar.php'); 


The problem is that the first one never gets called if you use the DB to store images. The second will catch it though!
