Importing avatars

Howdy

I'm working on porting a website over to Dolphin 7.  I've written a script that moves users, forums, articles, ads, etc.  But I'm stuck at how to import the users avatars?  It looks like bx_avatar_images controls this, but when I copy images in the /modules/boonex/avatar/data/images, and add an entry for this image into the bx_avatar_images table, the avatar doesn't show up for the user.  The value of the 'avatar' field in the Profiles table doesn't seem to matter, either.

help?

Not that I actually know how to go about this, but is there a possibility that you need to empty the server-side cache?

Yea, no, clearing the cache doesn't seem to matter, either.  I'm guessing there is some other table that links together the entry in the Profiles table with the bx_avatar_images, though I cant figure it out.
