A teacher at JC Harmon in Kansas inadvertently showed a classroom full of students a porn image during biology class; the teacher was using an overhead projector connected to his personal laptop when the image appeared on the screen.

A female student quickly snapped a picture of the image which contained a naked woman in a 'compromising' position and forwarded it to her boyfriend; he in turn sent it to another person and it then was posted to Facebook.

According to KCTV 5, when the teacher turned on the overhead projector which runs off his computer, a pornographic snap shot for a website appeared. Stunned and extremely uncomfortable Laura Lester said her daughter took a picture. It shows the laptop and projector and, in the background, there's an image of a naked woman in a compromising position from behind.

"I know my daughter was very uncomfortable," Lester said.

Lester said her daughter sent the picture to her boyfriend and asked what to do. Karen Winkel's son then sent the picture to a friend.

The girl and her boyfriend were suspended for inappropriate use of electronics - the teacher is out on paid administrative leave while the school conducts an investigation.

Winkel told KCTV 5 that she believes the real reason the two were suspended was because "the school was trying to hide something."
