A graphic background should simply make your web page look professional. Ask for different peoples opinions, preferably people in your target audience.
There are several styles of background graphic images. There are single picture, horizontal, vertical or the most popular is tiles. Tiles are rectangular and could be any size. All of these examples repeat as the default, unless you've learned to use styles.
Using flat colors as a background is very useful, especially behind text as it doesn't distract like most patterns would. Color gradients can also be used if you've learned styles.
Looking at this web page, you'll notice several levels of backgrounds. The far back should simply make the front pop, and you need to use the <body></body> tags. Anything with text should be relatively flat, because you want the text to be read. If you make text difficult to read, they simply won't!
You may use background concept in just about any container, like Tables, Div etc.
When you make your own web site, a good graphic background is a simple way to give your web page a nice texture. The texture is usually best if you make a seamless graphic background image.
