Photo Frame for Flickr
iOS iPad Photography
Photo Frame for Flickr turns your iPad into a stunning digital picture frame by showing a slideshow of photos from Flickr. No need to have a Flickr account.
Photo Frame can load the latest interesting photos, recent photos, search for photos and even load photos from the mystical Flickr panda Ling Ling.
If you have a Flickr account, Photo Frame for Flickr can also load your Flickr photos, your favourites and your contacts' photos.
Update for Flickr API changing to SSL only.
