There are some big advanced ones with commentary and multiple games, but they simply will not fit on this pages.
The best one I found so far is located at http://chess.maribelajar.com/chesspublisher/ and is very easy to use. Unfortunately the background is white so it will look really bad. :) But atleast it is a simple way of showing games.
To try it out here is a game Mediocre won against the strong java engine King's Out. All luck of course, but still. :)
