Security Code images are invisble

Sounds like your site may have problems with ASP sessions on the server.

There are a number of posts on this issue where I explain in more detail if you do a search on the this forum.

I'm also planning on creating a new version of the security images page in the next few days and I'm am presently trying to decide weather to move away from session variable and use cookie and encryption instead, or if there is some other means to do it.
