Robert Ray Horsch, 27, of Comanche Lane in Honey Brook, was arrested following an undercover investigation by the Pennsylvania Attorney General's Child Predator Section.
Prosecutors say the 2-month investigation traced numerous images of children engaged in "extremely sexually graphic acts and poses" back to Horsch.
Agents seized 3 computers and an external hard drive from Horsch's home. They found explicit images on the external drive.
Horsch is charged with two felony counts of sexual abuse of children for distributing child pornography, 10 counts of felony sexual abuse of children for possessing child pornography and one felony count of criminal use of a communication facility.
He's being held at Chester County Prison in lieu of $75,000 bail.
