Renders wrong in Chrome for me. Seriously guys? Good thing it's not an HTML5 gallery showcasing the benefits of open standards.
Some of these games (e.g. Gates of Olympus) explicitly mention Firefox 4, so the stable build of Chrome might be "too old."
What's odd, though, is it seems the background and image borders load last. Which is crazy - load your macro styles first, then the two-hundred-odd thumbnails.
