Background images can add a lot of zing to your pages, but they can introduce some problems, such as: Background images can add to the file size Images are very large, so a big background image can make your page much larger and harder to download Some images can make your page harder to read An image in the background can interfere with the text, so the page can be much harder to read Good images don t make good backgrounds A good picture draws the eye and calls attention to it The job of a background image is to fade into the background If you want people to look at a picture, embed it Background images shouldn t jump into the foreground Backgrounds need to be low contrast If your background image is dark, you can make light text viewable If the background image is light, dark text shows up If your image has areas of light and dark (like nearly all good images), it ll be impossible to find a text color that looks good against it

If you want an image that repeats seamlessly, you have two main options: Find an image online A number of sites online have free seamless backgrounds for you to use on your site Try a search and see what you come up with Make your own image If you can t find a pre-made image that does what you want, you can always make your own All the main image editing tools have seamless background tools In GIMP, choose Filters Map Make Seamless You can also do it by hand by offsetting the image (choose Layer Transform Offset Offset by x/2, y/2) and using the Blur or Clone tools to clean up the seams By default, a background image repeats as many times as necessary in both the horizontal and vertical dimensions to fill up the entire page This fills the entire page with your background, but you only have to download a small image
