Whilst some of those pics are quite evidently photoshopped in some cases (some to the extreme), not all of them are comparing the same photo. Models can look slightly thinner or fatter (is that the correct word - I don't think so but it is the opposite of thinner), depending on the angle they are photographed on. And you know what, some of the girls in the real photos are way too thin in them, never mind the fake ones! I personally value my life more than this and would rather be large and healthy than thin and malnourished and destroying my health & body.
