Twitter will launch its own photo-sharing service later this week if reports from All Things Digital are true. It's understood that Twitter CEO Dick Costolo will announce the service at the D9 conference in Rancho Palos Verdes, California tomorrow.
Flickr, the most popular photo sharing social network, has made a small but welcome update to its light box feature. The update targets iPad users specifically and allows images to be viewed full-screen in the browser, with a simple swiping motion enabled to cycle between previous and next images.
In a blog post earlier today Facebook have announced a new photo tags suggestions feature that uses face detection technology. Photo tags will be automatically suggested to uploads based on previous tagging data within your social graph.
