We just released a new universal iOS app that will let you batch upload photos to Flickr. The iPhone is the most popular camera on Flickr and we believe that this app will be very useful for Flickr users. PhotoLoader is easy to use and does one thing very well: batch upload photos (resized or in their original resolution) to Flickr!
