How to change template background image 7.3.3

The EVO background image is located at: templates/tmpl_evo/images/sys-bg-main.jpg

It's a tile about 1 inch square and it's repeated many times to fill the page. This is normal for backgrounds because the file size is very small and it allows your site's pages to load much faster. There are other advantages.

The code is located at:  templates/tmpl_evo/css/general.css

Lines 12 and 13 (approx) should look like this:

background-image: url(../images/sys-bg-main.jpg);

background-repeat: repeat;

The first line grabs the image.

The second line repeats it.

If you upload a new image, you can either use the default file name or rename it. If you do, you will need to reword line 12:

background-image: url(../images/new_image_name.jpg);

If you don't want the image to repeat, disable line 13:

        /*background-repeat: repeat;*/

Good luck
