/jci/gui/common/images/background.png
Determine the original file's resolution, create your new background with the same resolution using png compression
Upload your new background, overwriting the original one
Advanced Backgrounds Edit
The background image is rendered using CSS in
/jci/gui/common/css/common.css
By editing this file, you can use an animated gif as a background or scroll through a bigger image. This is restricted only by the Opera version used, since it cannot render many advanced CSS3 properties. If you want to customize the background even further, you can find the JS-based creation of the background in
/jci/gui/common/js/common.js
