Are we allowed to post photos that were already used in other threads like "Post a pic of Anything," as long as they're sitcom or other TV show related?

Yeah you can, it doesnt have to be TV related though. but if you want to upload a picture that someone edited or took the picture of... you should ask them first. :lightb:

Yes it does have to be tv related, if you just want to upload various personal pics - upload them to Chit Chat. The Photo Galleries are tv related only.
