All About Web Site Wallpaper
n Many Web sites use "wallpaper" to give texture to their Web pages. To do this, they add small pictures that "tile," repeating them over and over for an attractive pattern or texture. Use this procedure to add wallpaper to your site.
n Many sites have "free" or non-copyrighted pictures that are designed to work well as wallpaper. Small PNG and JPG files are best. When you have found one you like on the Web, right-click and save it to your local drive, then remember its name and location so you can include it in your Web site file.
n If you want the same wallpaper on every page, choose Tools > Page Layout Editor and add the background picture to the page layout. When you click Finished it will appear on every page that uses the current page layout.
n A large picture can also be used as wallpaper; to keep your site readable, use one that contrasts with your text. For example, if your site uses black text, make sure your photo is light enough to let the text stand out.
n If you use an animated PNG picture as a background or wallpaper picture, the picture will not be animated when you published the Web site.
