As eHomeUpgrade reports, now there is also a Flickr plug-in for Xbox Media Center available but for sure not not for the original Xbox Media Connect but for the mod'ed Xbox only. After Tivo (HME Flickr plug-in) also the Xbox got its Flickr plug-in but still there is nothing for the Windows XP Media Center Edition available?
Flickr is definitely the most successful photo sharing service and really ramped-up like a rocket over the past months. It's really handy to upload your photos from your mobile phone which is widely used by Flickr members and ehomeUpgrade's asked rightly: "So, what's up MCE developers? Why can't someone get on the ball and code a Flickr plug-in?".
The only photo-sharing plug-in for Windows Media Center, I'm aware of, is Kodak Easy Share Gallery (previously known as ofoto.com):
Kodak Share can be at least used to order prints (either via your PC or from your TV) as well as you can watch and share your albums as well as you can see your friends shares.
