Im having issues with the scaling of the cover photos;  if one of the included covers is selected, it scales just fine and looks normal; if I upload a cover photo through the profile page itself, it is also just fine.  But if I add a photo to the gallery in the admin then it scales way too large - and yet in all three scenarios the photos involved are 850x315.

Ok actually now I'm seeing that its pretty random; the same photo uploaded will sometimes scale correctly, other times not - meaning correctly in that it shows at 315px high and when not, it shows at 450px high.
