But its seldom done for two reasons: 1. Most people don't have the time, or the patience to re-sprite everything when an image changes. 2. Not every browser or search engine supports CSS sprites. The RPO helps by instantly creating sprites, returning them only if the browser supports them - EG: spriting is turned off for the Google search indexer. Most people are amazed to see the automatic CSS spriting, its very cool. Ed Robinson Spriting at design time is a great option. But its seldom done for two reasons:

Not that I'm suggesting it isn't pretty damn cool. Yeah, pretty sure I agree with EdRob on this one. Not that I’m suggesting it isn’t pretty damn cool.

Instead of a browser loading say a dozen JPG files, it loads a single mosaic then displays the different parts of the mosaic as each image. The process is fast and done automatically. For an example, see this SharePoint site: http://www.wssdemo.com/Pages/topwebsites.aspx Use a tool like Firebug to examine the mosaic. You can turn off the CSS sprites + other optimizations by using the ?rpo=off querystring parameter http://www.wssdemo.com/Pages/topwebsites.aspx?rpo=off Ed Robinson How it works: a page’s individual images (JPG, PNG, GIF) are combined into mosaics and cached on the server.
