Import flickr photos

Hi!

I just made a script using tumblr API and the flickr feed to import my flickr photos with links to the different sizes flickr give, the description and the tags. you can take a look at it in http://fotos.guidorossi.com.ar

I just wonder why tumblr doesnt do this? Its a great feature

Tumblr can only import photos from flickr using the RSS feed, but its not the same, it doesnt import others sizes, descriptions and tags.
