<span style="font-family: trebuchet ms,geneva; font-size: medium;">That's very true. However, the issue is not with the photo being used per se, but with the photos being used in an apparent attempt to defraud potential buyers.

Notwithstanding the fact that he apparently doesn't pay close attention to details and failed to notice that he got photos of two different models.</span>
