vBulletin Database Error! Attachment issues!

[M_Portiss]

Hey guys.. Another issue here.. It seems as though I keep getting database errors when my members are trying to upload pictures. This is the error I get:

MySQL Error : Got a packet bigger than 'max_allowed_packet' bytes
Error Number : 1153
Date : Saturday, January 13th 2007 @ 08:15:30 PM
Script :

Referrer :

Classname : vb_database

I have upped amount the users are allowed to upload. ( For example, .jpg is now at 1000000)

Any help here? What do I need to show you guys (Code wise..) to help me out?

Thanks in Advance!!
Matt
