OK I have fixed the issue, since badspot wants us to post an issue here it is:
if you have accidentally blocked avatars on Firefox then here is the solution:
1. select addons in firefox
2. go to extensions
3. find adblock plus
4. click options
5. click filter preferences
6. click custom filters
7. right click on ad blocking rules and select show/hide filters
8. uncheck the box next to "forum.blockland.us/avatar upload"
this will solve your issue if you accidentally block all avatar images.
