All the images found in a bust in Polk County, Florida were of children 10 years and younger.
Investigators say some of the images showed adults having sex with children as young as one.
Officials say the ages of the men arrested range from 18 to 53, with their occupations varying from a Domino's pizza delivery man and Holiday Inn front desk clerk to a Plant City Parks Department employee and an audio visual specialist for Disney.
The FBI has helped set up a phone number where you can call 24-7 to report any suspected child sexual exploitation.
The number is 1-800-843-5678.
