Hi Nate,

I think most people post here linked to someplace else. For example, I usually link here from flickr by using the BBC. But I've seen others link from several other sites, such as smugmug. I if I recall correctly the limit on image resolution is 1,000 pixels across. For direct uploads (click the picture icon between the "x" link and movie strip 4 in from the right on the quick reply screen), the file size (at least in my account) needs to be less than 194 KB.

Hope that helps,
Brant
