Hi shdesigns2007 to set an image for a back ground, You'd save and upload the image in your includes/templates/YOUR_TEMPLATE/images/ folder, then set it as the body tag's background image.

background:url("../images/your picture name here.jpg"); Or

background:url("../images/your picture name here.jpg") repeat;


if it needs to repeat itself.

Put the image into the includes/templates/YOUR_TEMPLATE/images folder.
