People who post their pictures on flickr have the option to let their photos available to be posted to other websites such as tumblr.
To post pictures from flickr, create a flickr account, connect it to your tumblr, then press the box with the arrow on pictures you want to post, and follow the instructions! Hope this helps :)
Haiku for the night:
The Postal Service
made my dreams come true tonight.
Fuck me, Ben Gibbard.
Today has been an extraordinarily sucky day so as a late birthday present, I’m treating myself to seeing Ra Ra Riot and The Postal Service in concert tonight :D
