How do I add "Image check" for unregistered users postings?

[f1vlad]

Hi,

On my forums I am allowing unregistered users post stuff because that's the nature of the project. Our admins aprove every message that goes in.

However, recently, spammer start driving our admins crazy. So I'd like to add one more step -- Image Text. The image will display random text and you'll have to enter it before proceeding with the post.

Does anyone know how to easily do it? I searched but couldn't find a hack.

Thanks,
Vlad
