I used this code for background image of <body> :
background: url("http://www.uplooder.net/img/image/39/45732833fc8fdcfd8277ca248d5b608f/QHD.jpg") no-repeat center center fixed;
This image acts really important for my website that if it misses, the whole site will be ugly.
How can I define another additional link so that if the server in which the image is uploaded stops working, the the image gets fetched from the other link?
