have a look to this new javascript tool I just posted on googlecode
it takes games from a pgn game abd dynamically allows for a chessboard
display on a web page.
it does not require to pre-process your pgn file into html pages.
it's based on various code, ultimately, I think, coming from the LT
PGN viewer.
