I agree with pryidevsblog, using Css background to make background for a image on webpage, it's easy to do. You can use it inline in your html code
< div style="background(URL_of_image) no-repeat top left;">content</div>
For making a back ground image, you can use it
<BODY BACKGROUND="bg.gif" BGCOLOR="color-code" BGPROPERTIES="FIXED">
or can take help from w3schools.
