I'm please to share a prototype of server side Deep Zoom generation, it's called codename Mooncake.

It can pull photos from flickr or other sites, generate an album up in the cloud automatically, and present it in a nice sleek viewer powered byDeep Zoom.

You can embed it in your web site or blog posts like these of my old pictures below:

Or you could just go make your own here: http://beta.redmooncake.net/

[UPDATE] Well, RedMoonCake has been covered at:

And I have to clarify one important fact that: I'm NOT the author of this project.  Allan Li from http://nxmix.com/ created it, and we are working closely with Allan to move forward this project.  My apologies if my original post sounded like I created it.  I like this project, and I'm really proud of Allan and this project.
