William Thomas, 58, was charged with an additional 26 counts on Monday.
Thomas waived his preliminary hearing on Tuesday.
Investigators say they found more than 1,000 sexually explicit photos of children inside his Falls Township trailer.
They allegedly found everything from child pornography, to children's underwear, to journals in which he wrote of his alleged criminal behavior.
Thomas was already charged with dozens of crimes involving five children.
