Windows/Mac/Linux (Adobe AIR): Free Adobe AIR application Flump downloads all the photos from a user-specified Flickr account to your hard drive. It’s a simple one-use application: You provide it with a Flickr ID or username, tell it where to save the photos, and click Start Flump. We’ve highlighted similar tools before, namely FlickrDown and Flickr AutoDownloadr, but Flump is the only cross-platform offering, and it’s also the most no-nonsense app of the bunch—perfect for backing up all your Flickr pics on a new computer. Flump is free, works wherever Adobe AIR does.
