My brother emailed me a naked photo of my nephew once.
He was around 4 and wanted to "dress himself" to go out.
When he came downstairs, he was carrying a football & wearing his cowboy hat & boots....nothing else. He looked so darn cute. That photo will be shown to him when he's older for lots of laughs. I'd post it here, but don't want to get FR in trouble for kiddie porn....
I was working on a computer once and ran into some shots I thought were pretty bad. Guy had a few (4 or 5) pictures of his kids, roughly 3 or 4, in the bathtub. They weren't explicit or anything, but I had that gut reaction of them being a bit old to be photographed in the bathtub. Instead of jumping the gun, I nosed around a bit instead and found a ton of family photos - birthday parties, weddings, vacations, etc. At that point, I realized that while those few pictures were a bit odd, it wasn't the result of a pervert, but rather someone who loves his family and his camera roughly the same. The scary thing was that if I'd jumped the gun and reported it, I could have utterly destroyed an otherwise perfectly happy and reasonably healthy family.
