in the css use this inorder to make it repeat.
(may need to make it a custom id or class)
#bgimage {
background-repeat: repeat;
}
that sets the image to repeat vertically and horizontally as well

if you only wont it to repeat horizontally use this.

#bgimage {
background-repeat: repeat-x;
}

by default all backgrounds repeat unless told not to with css.

also make the image in a div it will have a set width of 100 by defaukt with fulidness so it would be like this.
<div id="bgimage"><img src="path/to/image.jpg></div>
