Sorry, yes, I missed the Hardware/Development area. That would be the best place as part of an existing forum.
If these forums supported nested comments I agree that setting up a thread would work. Unfortunately it doesn't so comments are going to get separated from the original pictures. Imagine just 50 pictures with comments everywhere. It wouldn't work, then because no one used it because it was dysfunctional that would be justification for someone to say "We don't need a forum for this because no-one uses it". Do you see my point?
