I can find a user and see their available photo sets but when I select one and click to download, it only pretends to download the images. There are no permissions errors or anything and it creates folders for the user and the album and even counts down the images it's pretending to download (1/10, 2/10, etc) but nothing actually happens. Waste of time. Just download images from the photo pages on the Flickr website. It takes longer but unlike this app it works.
