DownFlickr is a Google Chrome extension that makes it easy for you to download high quality photos from Flickr.
With DownFlickr you can download both an individual photo or an entire photo set in the highest resolution available.
After installation, it adds a button to the toolbar and you use this to download the photos.
Whenever you want to download a photo or a photo set, just click on the DownFlickr button with the page open. It will then show you thumbnail of the picture(s) in a box with the “Photo Id” or the “Set Id”. Now click on the thumbnail of the picture you want to download or to download the entire set click on “Open all”. This will open the photo(s) in new tab(s). From there you can save (CTRL + S) it or directly set it as your desktop wallpaper.
By default the extension displays the first 30 photos, so if it’s a larger set you just have to click on “+30 ” next to “Set Id” for more photos.
