Precisely -- and absent a plug in from FT (which is apparently unworkable), the onus should be on the poster.

That being said, FT will be helped if the poster doesn't make the mistake that I made. A FT with pages which load badly, or are difficult to see (as oversized pictures make them) is not in anyone's interest.

As things stand right now, somebody can put up an oversized photo and not be in violation of FT's rules.

I believe TB should make it a hard and fast rule that this is not acceptable. Ideally, the best way to enforce that rule would be for the software to reject the picture, with a notice saying, "Your picture was too large to fit on our pages. Please see this explanation of how to solve the problem."

If, for technical reasons, that is impossible, than moderators, who are responsible for enforcing the rules, should simply take the pictures down and send the poster a PM giving that exact explanation.

IMHO, if a poster makes that mistake once, and receives such instructions, he will know for the future and not need to be told again.
