That will always happen with tables if the content won't fit in the browser window.

If the display is 600 X 800, you images are already too wide. Either reduce the image sizes, or let the page scroll with the small screen resolution.

Also, don't put size styles (width, height) and surrounding styles (margin, border, padding) in the same tag or css definition. Nest two tags, one with the sizes, and the other with the surrounding styles.
