Flickr is not new and is is certainly not unknown. But it remains one of my favorite tools and sites. My photos are at http://www.flickr.com/photos/waynesphotos/. That is, someof my photos are there. At this time, I am way behind in uploading my latest trip pics. But whenever I find some time, I move a few more to the site.
Dozens of great tools have been developed by third parties to expand Flickr’s functionality. For example, Flickr Grab is a thumbnail gallery showing over 200 thumbnails of any given set of Flickr images. A flash-based variation is Flappr where you can search for my photos under user wayne31r.
