Twitter has just announced the rollout of user galleries for tweeted images.

Galleries will show images shared using all the major services supported by Twitter, including yFrog, TwitPic, Instagram and Twitter’s new native images. Galleries can be found on the user’s profile page through the Web interface. They will display up to 100 recent images in chronological order. Tweets before January 1, 2010 will not show images or videos.

Twitter profile pages will now display thumbnails of the user’s four most recent tweeted photos on the right sidebar, right under their vital Twitter statistics, and clicking ‘View All’ opens the user’s gallery in the current window. This is the first new feature Twitter has built upon its native image sharing, which launched this summer. Until that launch, third-party services handled image sharing on Twitter. The new user galleries will support those services, but the galleries themselves will only be available from Twitter’s website.
