Micro-blogging service Twitter launched a photo and video search service on Wednesday that lets users own the rights to the photos they post, makes search results more personalised and make the results of more authoritative tweeters prominent.

Chief Executive Dick Costolo unveiled the service at the “D- All Things Digital” conference. He said the service will be rolled out to all Twitter users in the next couple of weeks.

Costolo said the service will eliminate some friction that users face when trying to post images. It will also allow links to videos to be posted, but users cannot upload videos.
