I think I may also have seen this bug last year and could not work it out.

Anyone else have the issue if they upload a landscape photo it then renders really much smaller than original size when you click on it, but if you upload a portrait pic it renders nice and big? (Even if the portrait size was cropped from the same landscape format pic).

I know portrait cropping would help judging using phones, but I had figured landscape would help people that use computers to view pics. Not so. Portrait seems to be best there, also
