With this layout you do not need any repeating images to color the side columns. The side columns get their background color from the main #wrapper div. However, for demonstration purposes I am also using a repeat-y image on the #wrapper to give the left column a different background color. The right column will get the #wrapper's background color.
Here is the image that is being used:
The layout is set up with min-max widths on the #wrapper div to give it some flexibility but it can easily be set to a fixed width layout by removing those min-max properties. Just remember that IE6 does not support min-max properties so it would require an expression or javascript. Another way to cater to IE6 would be to just give it a defined width other than the percentage width that is used in this demo. That will keep it from getting to small at reduced viewport widths.
