Jack Dorsey on the Twitter Blog:
>Over the next several weeks, we’ll be releasing a feature to upload a photo and attach it to your Tweet right from Twitter.com. And of course, you’ll soon be able to easily do this from all of our official mobile apps. A special thanks to our partner Photobucket for hosting these photos behind the scenes.

Good move, I like that they don’t have to bear the cost and scaling of photo hosting. ((No doubt there are some back room deals that benefit both parties, so when I say “cost” I really mean all of the cost.)) I also like that Twitter is grabbing hold of this segment of the service — this needs to be controlled by Twitter, for the sake of Twitter.
