<p>I just got through uploading every last one of my photos to Flickr over the weekend, with an Ethernet cable snaking across the floor from the router to my iMac, and a new app on that iMac to do the work. The app is called F-Stop, and while it's a little glitchy in its UI, it was rock solid where it counted: pushing around 22,000 JPG files up to Flickr.</p><p>Previously, I recommended the Finder as a good way to reliably send big batches of pictures up to Flickr, but two things changed my mind. One was when I left the upload running overnight and found that the Finder, although it had apparently finished uploading, had only sent around 2,000 of a folder containing 3,000-ish images. Because there's no way to compare a list of what has been uploaded to Flickr against what's on my Mac, that meant starting over.</p><p>The second was that I spotted F-Stop in the Mac App Store, a free front-end to Flickr that is powerful but idiosyncratic. The app offers a fantastic way to upload batches, and you can even queue up batches and have them upload one after the other.</p><p>Over the past week, I've put all the photos I've ever taken (excluding film, anyway) into a single Lightroom library, gathering everything from iPhoto and Aperture into one place. I hate iPhoto, and I have all my RAW photos already edited in Lightroom, so that seemed the best option. I then exported everything to 70%-quality, full-sized JPGs, organized into YYYY/Month folders.</p><p><a href="http://www.cultofmac.com/262083/f-stop-the-best-flickr-bulk-uploader-for-the-mac/">Keep reading...</a></p>
