TMZ has obtained the mug shots of the two people who were arrested for allegedly trying to extort John Stamos for $680,000 over photographs that were taken of the actor at a party back in 2004 ... apparently the duo thought the pics were compromising but we're hearing it's a lot about nothing.
Allison Coss and Scott Sippola were arrested on December 2 at a Michigan airport during an FBI sting operation.
