Find and save full size photos easily from Flickr, with Flickr Downloader
Flickr Downloader is a free utility that lets you locate Flickr images to save on your PC.
The use is as easy as viewing a list of thumbnails and selecting what to download. Note also that you can open the on line page of a particular image by just clicking on its thumbnail.
Feel free to load a lot of thumbnails on a single page of Flickr Downloader but you need to have a really fast internet connection.
