I've run into it myself. I read up on it a while back and if I remember correctly, it's an "Apple thing". I don't remember the details and a lot of the explanation was techie talk I didn't really understand, but there's an extra step in the software that SOME sites have that will post Apple photos correctly, others will not. I may be wrong (it's been a while), but if you Google it, there will be a ton of posts describing the same problem.
