Ideas to prevent adult images being uploaded to photo site

Question

I run a small photo site. It has recently come to my attention that a number of the images being uploaded are adult in nature. I need a good simple way to prevent the uploading of adult images if possible. Any ideas would be helpful, thanks.

Also, the site is running using pretty much PHP, JavaScript, and flash. http://superlame.com

Answer 1

I suggest you take a look at nude.js. Perhaps that's all you need. It seems like the perfect solution to your problem.

Answer 2

Here's a PHP port of nude.js, I've just tried it and , to some extent, it seems to be working.
