Flickr Viewr is an application for viewing images from Flickr. It is very simple to use! All you have to do is write the tags you want to view images from. Let's say that you want to view images from the beaches in Rio, you can write "Rio,beach" in the tag field, and then click "Feed me with pics", then the images will come to you desktop! Each image will show for approximately 5 seconds, then a new image will automatically load.

You need to be registered with Flickr to use this, but it's totally free, and takes 20 seconds to sign up! You should do this anyway, because it's the best online photo-gallery out there!
