I'm the host 
but I'll read up PHP. Thanks for the help
EDIT: Umm I'm sorry to bother again and this is not really punbb related I'm kinda lost again. I checked my settings in php.ini and modified the part that said upload_tmp_dir to say "/tmp" now I'm not sure if php's / is the same as apache's / so I created `n tmp in apache's chrooted dir but it still gives me the same error what am I missing? or where can I go read up on what I'm missing? I found this "http://www.php.net/manual/en/configuration.changes.php" but it didn't help me
P.S Please excuse the errors I'm a little tired at the moment
now can anyone tell me where the file goes from when the upload button is clicked till the file is in the img/avatar directory, or preferably how to figure that out? Any help would be greatly appreciated
