It can be difficult to upload, organize, describe and create tags for hundreds of digital photos at one time. But the new revamped Flickr Uploadr 3.0 introduced last week made this an easy process.

The first time Uploadr is started, users will be asked to authorize it with Flickr, but you don’t have to do this now. Version 3.0 lets you work offline, adding and organizing photos until you are satisfied before the actual uploading begins. I would recommend authorizing from the start because the process seemed more streamlined to me. When you are ready, click “Sign In,” and you will be directed to Flickr.

Photos can be dragged into the Uploadr individually or in large numbers. My first batch contained 171 photos.  Click the “Add” button in the upper left hand corner. When the window opens, navigate to your photos. I selected all of my photos and hit “Open” to place them in the Uploadr box. Once the pictures appear, select a photo (or as many as you like), and start adding titles, tags and descriptions. The Uploadr also allows users to choose who can see the photos, define safety levels and content type, and create sets. Hit the large “Upload photos” button on the right hand side of the page.

At this point you can walk away and do laundry or something. It could take a while, depending on the speed of your internet connection and how many photos you are uploading. The cool thing about this new Uploadr is that you can go ahead and immediately add and organize more photos — all while the first batch is still loading to Flickr. I added three sets of nearly 500 photos. Out of those, only two images weren’t uploaded, which is pretty amazing if you ask me. A message comes up saying, “Darn! Some photos didn’t make it.” The culprits are shown in the Uploadr screen. Just tell it to try again, and the remaining photos will join the rest.
