Avatars

[Gratisites]

I'm storing avatars in the file system and (slowly) developing a custom app that will use them. Avatars look like this:

Where 1234 is the userid, but I'm curious as to what the "5" refers to, my avatars seem to be numbered from 1 to 5 on that variable and it'll make my life easier if one of you knows what that is. Thanks.
