The software Downloadr is more than just a tool to backup Flickr accounts. It can perform a search for photos on Flickr using fulltext, users, tags, places, sets, dates, groups and favorites. It can display a maximum of 250 photos per page and download all selected photos at once.

Only Creative Commons photos are searched by default but that option can be disabled in the search form. The easiest way to backup Flickr accounts would be to enter the username and download all photos that are found. This is obviously only working if the user has made all photos publicly available. Private photos cannot be downloaded this way.

There is however another option to download all photos of a Flickr account. Downloadr comes with the means to authenticate a user. Once a user has been authenticated by providing his login details the function Complete Backup can be selected.

This option will download all photos from the authenticated Flickr account to the local computer. The pictures will be downloaded in one go and the program handles even large amounts of photos fine.

The download of the software program will download a file called updatr which has to be executed to download the rest of the program files. Downloadr itself is a portable software program requiring the Microsoft .net Framework.
