If you'll recall, it was only a few weeks ago when Flickr announced Aviary was replacing the vanished Picnik as the main photo-editing tool on the site. Now, continuing its ongoing makeover, the Yahoo-owned image hosting service is introducing yet another feature. Uploadr, as it's very cleverly dubbed, is an HTML5 web apparatus, which Flickr says will make for a "completely new uploading experience." There's a few major attributes Uploadr brings to the table, including improvements in the speed department, a drag-and-drop UI and bigger file size limits for paid and free users. Flickr notes that folks will now see a boost in uploading speeds of up to 30 percent, while "some" international users may see a spike of somewhere between 50-60 percent. As for file sizes, the limits have been bumped to 50MB for Pro hogs and 30MB for those enjoying the freebies. Uploadr's set to be rolling out over the "next couple of weeks," and is currently offering browser support for Chrome, Safari and Firefox.
