The one says type in the above letter and numbers. These letters and
numbers are an image and slightly off centered and slanted.

Thanks

There have been some recent posts on this topic.

I was also interested but didn't find anything useful - sure there
were references to some sites that used it, but how to implement ??

Actually to answer my own question, I think the sites in question
linked to various random images and obviously some file which
contained the translation into characters, so each time a different
set of characters is used and a different response is required.
Perhaps we should both keep watching

Well, Tony

I did a bit of searching and this method is called captchas http://captchas.net/

To use this technology, your web pages have to be generated dynamically by any programming language like PHP, JSP, Python, ASP,
Perl. To encode the password the Message Digest Algorithm MD5 is required. It is part of most of the named languages or can easily
be installed.

So for an ordinary page it may not work (unless one can simulate this using JavaScript)
