A lot of times a scanner will kind of crop a photo when you don't want it to. I try to pull it away from the edges of the scanner about a 1/4" to avoid this problem, but it still happens. Especially on white or black covers. Putting a backing board behind it helps too. Gives the scanner something to "grab" behind the image.
More than the picture though, their wording in the listing really needs work. No info, high price, and negative feedback. Makes it hard to want to buy it.
Have you tried messaging them, and asking for more pics or info?
