Surfbirds advises on posting pictures,
with guidlines on sizes etc.
On the common birds section, just look at the variation. What is the point of having guidelines if only to be ignored. It is not fair on the ones that stick to to the rules. Posting pics that go off the page is not serving any purpose or doing the poster any good anyway. Bigger is not always better.
The guidlines might as well be removed and we can all go for a free for all.
