it is a php program which onyl converts simple input tags to html code for inserting an "iframe" ..

looks not so hard to implement… I like chess and it would be a very nice implementation we can "call" for an iframe or image part..

I rated it up!
And @Gunnar : you should rate it up too!

I found another ( better ?) solution - using an existing server for such chess image:
( think of FEN postition "5N1k/6p1/7p/4P3/pp2Q3/4q3/1P4PP/2b4K/" i send this "position" to the site http://www.eddins.net/steve/chess/ChessImager/ChessImager.php?fen= and get as an return the IMAGE constructed:
( ==> I have only to construct THIS url-adress with the entered position!)

[[image http://www.eddins.net/steve/chess/ChessImager/ChessImager.php?fen=
5N1k/6p1/7p/4P3/pp2Q3/4q3/1P4PP/2b4K/ ]]

gives

The software can be used on your own server ( hallo WIKIDOT TEAM! ) from http://www.eddins.net/steve/chess/chessimager

or
with some extra codes like size, coordinates0on, colors, style
&square_size=25
&coordinates=on
&ds_color=(70,109,186)&ls_color=(255,220,175)
&piece_style=style ( default=merida )

[[image http://www.eddins.net/steve/chess/ChessImager/ChessImager.php?fen=
5N1k/6p1/7p/4P3/pp2Q3/4q3/1P4PP/2b4K/&ds_color=(70,109,186)&ls_color=(255,220,175)&coordinates=on&square_size=25&piece_style=leipzig ]]

I think - this is easier as any php installation… ( as long as the serverside works..)

I created a little howto: http://community.wikidot.com/howto:add-chessdiagrams for adding chessdiagrams on a wikidot page with Steve's ChessImager..
