ChessImg.com is a website that allows users to create chess diagrams for use in forums, emails, blogs, websites, twitter, facebook
The site supports square highlighting and multiple image sizes.
As an example, see the image below:
I like jinchess.com. The position is set up on the parameters you pass to it. Check out the source on my website or quote this message.
This is handy. Any other diagram creators people are fond of? What’s the one that creates the interactive diagrams that you can click through which appear in many articles on this site?
I also have interest in this and wonder if the same programs (as these listed above) are suitable for loading your own game files, archiving and reviewing games, analyzing positions, etc.
I realize this is probably a pretty pedestrian query, but I am also a bit behind the times in terms of software and technology in general. (My kids always say this, and I will admit it!) So the program(s) that archive games and facilitate analysis/graphics may be obvious to most. I actually tried to download some freeware (I forget the name at the moment) to do this, but it didn’t work. Maybe better stated: I wasn’t successful at getting it to work.
Appreciate the posts in this thread and any additional suggestions that members can provide.
It has been a while since I last visited the jinchess site, but I seem to recall they had a way of selecting the board and pieces as well as entering the diagram when I first started building my web site. It then created a parameter string which could be cut and pasted into html code, but I didn’t see it when I revisited the site today.
The ones above aren’t chess database programs (which is what you’re looking for.)
You may want to look in this thread, for the main candidates. Or PM me and I’ll send you some links. 
Chessvideos.tv has a nice diagram generator too.
Is this a problem position? Place white’s king on the board in such a way that the position is legal, then figure out whose move it must be, then figure out what the last move was, or something like that?
Could be an intriguing problem, if so.

It is on my web page. Find that diagram and highlight the hidden text on the right hand side. I think it was by Sumllian (sp?).
