There might be a possible clue for the web gurus re. missing avatars. When I open a thread that has postings from members whose avatars are no longer there, the loading of the page seems to take longer (the little doohicky spins longer) and then it finally puts the avatar block up but without the avatar. It appears to be trying to put them up, but can't.
This just happened twice in a thread containing postings from Jim Liberty (whose avatar is apparently on vacation).
For the record, mine has never disappeared. Don't know if size is the issue.
Hope that might help...
