I did the importer to my real server after testing it for 4 weeks and just now I realized that the Users Avatars are not being imported, and if I copy then manually to my new folder, the numbers are totally off, since on my old forum I had ID missing (deleted users??) and on the new forum the ids start a 1 and go up one by one.

How can I match the users avatars?
What was wrong?
Maybe I know what was wrong: the /useravatars folder didn't have permission to execute (was only 666). Could be that?
If this is the problem, what would be a solution?
The site is already open the the users so posts already haven occurred.
I also already change the forum folders name to match the old forum, so will be kind trick to roll back...
Can I import only the users? (or even better, only the avatars?)
