Is there any scripts out there that will scan an image for 'flesh tones'?

I am running a small social networking site. One of our features, as most have, is the ability to upload images. The site is growing rapidly, and I find it impossible to moderate and enforce the terms of service, the most important term being 'no pornography'.
Are there any basic scripts that can examine a JPEG or GIF and report a percentage of chance that the given image is pornographic? I could then use this to generate a check list that moderators or myself would examine by hand.

might be of use.

Interesting thought, delphian, but wouldn't a picture of a face, for example, have a large portion of the image in the flesh tone range?
Flesh tones tend to vary, too, of course.

Maybe you can stave off pornography uploads by threatening to ban users who do?

The way that I have tackled this problem has been to implement a small 'flag this page' feature on each page. When clicked, it opens up a simple little dialog box that enables viewers to type a reason why they think the page is offensive and then send that to the site admin (me). This is similar to the way in which blogger.com works.
Whenever I get one of these emails, I check out the page and either mask it from public view or, if it contains pornography, just delete the entire account.
This seems to work really well and I only actually get about 3-4 flags a week (from thousands of users on the site). I think once people realised that porn got deleted immediately, they stopped trying!
