:shrugs: I've got nine corns and pictures of only half of them. Hopefully we will get a camera some day, but first come the student loan payments, the car payments, the house payments, the groceries, 700 frozen mice order.....

It seems like every time I get enough saved up it gets blown on some more corns.
If the breeder was working with corns on the side or as a hobby, then no it's not terribly surprising they don't have pictures. Who knows, maybe they had pics at one point but their computer crashed. Not everybody who breeds corns is in love with them like the people on this site.
There are a lot of corn breeders out there who just keep them as incidental stock, and their real projects are things like chondros and hogg island boas etc. In my experience these herpers rotate their corn breeders periodically and don't bother to keep a photographic journal of each animal's life, because that animal's stay in their collection is probably limited anyway.
