So what if you didn't make it.

If they (the athorities) wanted too they could bust you for any amount. Usually the way one gets in legal in trouble is when a family member/friend etc... finds the material and turns them in.

I believe that the current law is one year for each picture.

True it may seem like it'd be wasted effort to go after a person with 1-2 files listed for available download but remember that where there's smoke there's fire. If someone has just a couple files for download doesn't mean that is all that they have collected.

Remove the content and don't download it to begin with is the best suggestion.

As for the nudity law, if the person is a nudist it's ok if they are nude but they can't be posed. They law can get you for any nudist images that aren't entirely up to snuff.

It's not about your definition or beliefs but the definition in Blacks Law dictionary that most legal pratices go by.
