Avatar problems (imported from phpBB)

[Divvy]

Hi mates,

I need a little help here...
I did an impex import from phpbb2 to the last version of vbulletin.
Everything worked except 2 things:

Avatars and signatures is not showing in the posts, profiles, etc...
Please take a look:

Well, I solved the signature thing making this:
Usergroups --> Usergroup Manager --> Signature Permissions --> Allow Image BB Code --> YES


Now, my problem is only in avatars... they imported fine. They don't show in the forum but some users have their avatar displayed in their user cp. Anything to fix this?
Take a look:

Can someone help me?
