flump is a tiny Adobe AIR app. for downloading photos from Flickr.
You supply a Flickr ID (it could be your own or someone else’s) and the tool will download all the public photos from that Flickr account to your hard drive.
flump downloads the original images but only if the Flickr account owner has set their account permissions to allow the original images to be downloaded.
The app was originally developed by Mike Chambers and Lee Brimelow of Adobe and the full source is now available on Google code.
