good idea
- I do this with different usergroups and promotions
Set up 2 Usergroups:
1) can see only small images
2) can see small and large image
Usergroups and Permissions / Usergroup Promotions /
- Adding or Editing a Promotion
http://www.vbulletin.com/docs/html/m..._add_promotion
Usergroups => Promotions => Add New Promotion
Check: Usergroup1 - IF posts > 0 THEN move user to Usergroup2
I guess a hard code hack could be made, but this makes it hackless.
