Reference original report made about PhotoPost:

ReviewPost is also suspectable to "4.6 UPLOADING IMAGES WITH ARBITRARY CONTENT" of the same report.
I've just tried it myself and it does indeed still work.
A fix would to to resize or process each uploaded image through imagemagic to ensure that they are correct (as suggested in the initial report made in March). If it fails to resize, junk the image and report that to the user in the uplaod routine.
Not quite a bug, and not quite a suggestion really.. best place I can think of posting it is here.
