No, at this time Yahoo! Site Solution does not allow you to add or change background images (images that appear behind text or images). If you choose a site design that includes a background image, that image will appear on one or all of your pages (some layouts may not include the background image).

To change or remove a background image, you'll need to choose a new design. Learn how to change your site design.

Remember that although you can't change background images, you can always add your own images to your site, including a logo. Learn more about images.
