One thing that seti does is looking for repeating non natrual patterns no?
Near the end of Wow.JPG this pattern can be found. As a matter of fact, the only thing after this is "FF D9", which someone mentioned is the "eof-signal" for jpg-files.
I don't know enough about photoshop or other image manipulating programs to say that this is manually added.
It just looks way to out of place to me.
