I loved knowing that all my imported photos in iPhoto were automatically backed up to Flickr, so if I ever lost my laptop / backup drives, I’d be able to safely re-import my photos again. Unfortunately, as software advances, some things don’t keep up. I’ve upgraded to Yosemite (and soon El Capitan), and with that, iPhoto has been upgraded to Photos, and this app no longer works with the new Photos.
I’m going to switch to Flickr’s native Mac uploader, but I doubt it will be able to detect the duplicates that I’ve already uploaded, which means I’ll need to upload all 60GB again. (Edit: actually no! Flickr’s native app did indeed detect all photos I have already uploaded with this app! Fantastic!)
If you’re using iPhoto still, this program is fantastic!
