Your code is wrong, assuming you added a bitfield can_upload_img:

PHP Code:

if($permissions['genericpermissions'] & $vbulletin->bf_ugp_genericpermissions['can_upload_img']){
echo "welcome admin";
}else{
print_no_permission();
} 


Anyway, it's not a good idea to user standard bitfields for custom permissions, as you will run into problems sooner or later if you do so.
