Photo Posting Clarification Needed

[tomustang]

The owner of the forum might be sued by the owner of the rights of the photo if no written permission has been granted.

This is true, in fact people are sue happy. But in a forum like this fair use is always the case, which would lean more for the owner of the photo losing the case.

Fair Use defined:

the fair use of a copyrighted work, including such use by reproduction in copies or phonorecords or by any other means specified by that section, for purposes such as criticism, comment, news reporting, teaching (including multiple copies for classroom use), scholarship, or research, is not an infringement of copyright.
