FlickrDown solves a big issue when downloading pictures from Flickr: it enables to download many of them simultaneously, without having to open and save them one by one.

The good thing about it is that you don't need to be logged in Flickr, nor even have an account. You can perform a search by e-mail address, username or even tags, check out the results on the program's interface and just select with your mouse the pictures you want to download. Also, if you click on any thumbnail you'll open the actual photo on Flickr.

The only thing I missed was having a "select all" and "select none" option, which would make it even easier. In any case, FlickrDown is definitely a very useful, convenient tool for all Flickr lovers and compulsive photo downloaders.
