How about creating a sticky tutorial or similar to show how to display images in the forum?
Seems like a lot of people have trouble linking images from Flickr and other sites, even uploading to the LFPF server.
and somewhat related (this is more a suggestion), why not encourage users to not reply re-linking the image discussed or commented. We could make threads a lot shorter this way. Just quote the text so people know which image they're reffering to, not the image.
