Background repeat image

Using ‘fullwidth’ for the web page, we are trying to add a repeating pixel image for the back ground.
The only method we have found to add a background image is:

[section bgcolor=”#232323″ textcolor=”#ffffff” padding=”60px 0px 60px 0px” image=”/image/xyz/jpg”]

Problem with this it is using an unnecessarily big image as the image above needs to be large

All we need is for example:

background-image:url(xyz.gif);
background-repeat:repeat;

How can this be done using fullwidth, so we can set a different background image per section ?

Thanks
