I'm in the process of giving visitors to my website the opportunity to leave comments on certain pages. Since I would like to do this without requiring email activation I though about using some form of image validation. I think I found a good way and even made a page about it. I would like to hear some comments about the implementation and how to make it better. Unfortunately I can not post the source since the script requires small images to be loaded which I can not post to this group.
