Some help with Avatar import from phpBB
 

Hi.
I'm migrating a board from phpBB2 to the latest version of vB.
I'm having trouble with the avatars and I would like to get this cracked if possible.

If I import users and select to import Avatars the process seems to hang at random points* normally 100 or so in to the process. I've found that if I click off to another link and then click back on to import the process continues.
If I look in the vb_users table I can see the users have imported and if I look in the custom avatars table I can see that there are entries in there.
So what's happening?
