A Garner man has pleaded guilty Tuesday to transmitting child pornography over the internet.

Gary Wayne Robinson, 28, entered the plea in federal court before Judge James C. Fox.

Garner Police were alerted to Robinson after they say he engaged in an online chat with an undercover officer in New Hampshire in October of 2009. During the chat the two discussed trading child pornography and Robinson sent several pictures of children to the undercover cop.

An investigation revealed over 700 photographs and 59 videos of child pornography were found on Robinson's computer.

Robinson faces up to 20 years in prison and up to a life-term of supervised release. Robinson also faces a fine of up to $250,000.
