The FBI doesn't know where these pictures were taken, but they're hoping someone might know who the man is.
They believe he's involved with the exploitation and sexual abuse of a child. The pictures were taken from video sent to the National Center for Missing and Exploited Children in November 2012.
The man is described as a white male, in his 30s or 40s, with a receding hairline and wearing wire-framed glasses.
The FBI hopes the background, showing a blue sofa chair and a picture hanging on the wall, as well as a shark logo on the man's shirt, will help them track him down.
