I'm in the process of (manually) upgrading a site (www.reverse-therapy.no
) from ver. 1.x to 3.x. The old site had a nice background image, included in the template (jbelevate2). New template (Lifestyle2 from Joomlabamboo) doesn't seem to have any background image. Is it possible to use my own photo as a background? If so - how ? Will an image like this have any negative effects on the pages, like mobile friendliness, speed etc.?
