I want to use CoolIris (www.cooliris.com) in my asp.net website and it should take images from my website (images folder), not from external sources like facebook, flickr, youtube or external rss feeds.
If you publish a Media RSS feed, Cooliris (the browser plug-in) will work with your site. See: http://www.cooliris.com/developer/reference/media-rss/
To embed the Flash wall, follow these instructions: http://www.cooliris.com/developer/documentation/?p=embed
