Ok, so I was just browsing, and came across these 2 sites...
during my web dev browsing and noticed the same smug smiling girl on both sites. Just struck me as funny / odd that out of ALL the sites, and of ALL the images, authorize.net is using the same image source as some second hand traffic generation site. You'd think a leader in CC processing would be paying more than 2 credits for a web image.
(Of course, I suppose the other site might have just ripped off the image from auth.net too)
