it's possible??
at same way of ezboard...
Thanks

Link to what? Their profile? If so, open the postbit_avatar template and replace whatever's in there with this:

no but instead the avatar stored locally on the server...
it's linked ... as other board...
you understand me??
excuse for my poor english :(

Oh, I see what you mean. Well, I suppose it's perfectly possible...but not necessarily advisable. Avatars take up very little space, and hot-linking is a baaad idea, which, unfortunately, will be inevitable if you found a hack for this. As it stands now, though, vBulletin users can enter a URL and the script will go and make a copy of that file for the local server.
