Chess diagrams

Can anyone recommend a really good chess diagram generator?

I really would like to find one that let's you add numbers to the squares of the board -- for example, if you wanted to show how corresponding squares worked.

Free is, of course(!), better, but I wouldn't mind paying money for a really good program.

Thanks to all that reply.

I've used this to make simple jpgs, and it works ok for that. But I guess you're after something a little bit more high tech...

Hope this helps 🙂

Yeah, that's a good site, but I was hoping with some more features.
