[Plugin: piflasa] Picasa Album Pics not working in the Post

I have a blog post http://www.iwebie.com/jog-falls-karnataka wherein I need to display Picasa Album as a Slideshow. I am using the Piflasa (http://wordpress.org/extend/plugins/piflasa/) plugin. I have added the following line of code in my post as per the syntax that needs to be used for the plugin. The images don’t appear in the post

[piflasa]http://picasaweb.google.com/data/feed/base/user/hemanth.balaji/albumid/5262964144097152481?alt=rss&kind=photo&hl=en_US|400[/piflasa]

But when the same plugin was used in my friends post in http://www.iwebie.com/fiat-500-launched-in-india it worked perfectly. I have made my Album Public Already.

I need help to display images in the post using Piflasa
