Downloadr is a top of its class application as it provides all the functionality one would expect from a downloader with ease of use that makes it possible to start downloading photos from Flickr in just a few clicks.

It supports authentication when needed but can also be run by users who do not have a Flickr account. A search can be conducted by entering tags, a username, fulltext or places with additional filters like dates or creative common photos available.

50 Flickr photos are displayed per page by default which can be changed in the options. All it actually takes to download the photos is to select some or all that have been returned by the software followed by clicking on the Download selected button. Downloadr will always download the largest available photo size from Flickr.

Photos can be previewed in a larger size in the application. Information about the photographer, tags, exif data and photo are retrieved and displayed in the preview window as well.

A right-click on any search result displays various additional options including related tags that can be searched for, loading the photo page on Flickr or searching for additional photos taken by the user who took the photo.

Authentication is required before private photos can be downloaded. A handy backup option is provided to backup all photos in just a few clicks.

Exif and IPTC data is automatically written so that the information are preserved in the photo downloads. The developer of the Flickr photo downloader has created a screencast that demonstrates the functionality.

Downloadr is compatible with most Microsoft Windows operating systems including 64-bit editions. It requires the Microsoft .net Framework 3.5.

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.
