There are lots of ways for you to upload your photos to Flickr, in addition to using the web-based upload form once you have logged in. You can now download an installer (.exe) that allows you to bulk upload photos into your Flickr account directly from your PC. Once you install the Uploadr, just drag and drop in your photos, add some tags, and you’re done!
