I don’t know how many times I’ll put myself in this position. I have all my photos on Flickr. But I need to have them on a local drive too. I have a partitioned hard drive, and a special folder. And every now and again, my hard drive dies, or I accidentally delete the folder somehow. An then I have to download all my photos from Flickr again. Which is a whole load more hard work than it should be. You’ll need a third party app, because Flickr doesn’t provide a facility to download your entire photostream.
There are plenty of apps. Most of which haven’t been updated for years. Some of which contain malware. Others fail to download exif data, or turn sets into folders or are otherwise intensely laborious to use. Bulkr is great but costs $30. FlickrEdit, the tool I’ve previously used, is now too buggy. Should you find yourself in a similar situation, I can vouch for Downloadair. Running on Adobe Air, it’s got a pleasant UI, is easy to use and works well.
There are only two downsides. You have to click on each album to download it. I have more than 400, so it took a while. And it adds a string of unwanted numbers to the file name. Very irritating. But it’s free, and does everything else perfectly. It even picks up where it left on mid download if the PC crashes. So I can live with the flaws.
