Your web page. Change the white to black. It would help make the images more easily seen. In spite of the small proportions of the images, they are still way to big file wise. Decrease them to about 40k.

With the white background, the screens look very dark. I only looked at one, (because the files were just to damned big) but it looked nice.

Please do not argue. The files can be 40k and look exactly as good as your monster ones.
