That is so weird. I get a DNS error on the first one, but the second one works fine, and yet they are supposedly hitting the same server. I even copied the server from the second one into the first URL, and still get a DNS error.

However, after looking at the two picutres, it is tough to tell. The lighting in the two pictures is so radically different. The one in the second picture has puffier cheeks and appears to have a much more freckled body (indicated by her reddish hair), and that is something that would not change even given a few months time, so I'd have to say no they are not the same person. But, like I said, the lighting in the first picture could just be masking the freckles and it makes it very hard to really tell.
