If you have a Flickr account and a Windows Media Center Edition of XP or your trying out the Windows Vista Beta that includes the Media Center then you really need to check out ‘Big Screen Photos‘. This add-in for Media Center will allow you to view yours and anybody elses photos from Flickr on your TV screen.
If you have an XBOX 360 setup as your Media Extender then you don’t even need the PC hooked up directly to the TV as ‘Big Screen Photos’ will work through the extender.
The software is currently in free beta and you will probably need to purchase it once it’s out of beta but looking at the screenshots and the functionality list this looks like something I would buy.
