With Google set to close the Picnik shop on April 19th, it was obvious that Flickr had to go out and seek a fresh replacement. Today, the Yahoo-owned service is announcing Aviary (a Jeff Bezos-backed startup) as the new photo editing tool on its site. Along with promising to be simpler and speedier than its soon-to-be deceased predecessor, Aviary brings expected features like cropping, rotating, sharpening, red-eye reduction and cosmetic whitening, just to mention a few. Of note, Aviary is written in HTML5, opening the doors to become useful on a handful of slates and handsets. Flickr is set to commence the rollout later today, though it may take a few days until you can check out the changes.
