To remove images you would need to change

$comment= $bbcode_parser->do_parse($longcomment, 1,1,1,1);

to

$comment= $bbcode_parser->do_parse($longcomment, 0,1,1,0);

I've not tested this but basically the first 0 turns off html and the last 0 turns off image code. Please try it and feedback.

VBSEO for avatars:

My avatars are in the format url/avatars/username.gif?datelinestamp
I can use this method, due to the fact that usernames are unique.

The code I use on the hack is

<img align=\"absmiddle\" src=\"{$website}/avatars/{$row['username']}.gif\" width=\"30\" height=\"30\"></img>

place is where you want the avatar to show
