The Flickr Widget is a gateway to Flickr photo collections:
You can navigate through photos or start a photo playback that changes at an interval you can set. Drag-and-drop uploading makes it easy to put bunches of photos in Flickr in one go as well as customize the information that goes with them either as a batch or individually. You can also edit the information and search that information for matching photos.
* You have to establish some of these features in a Flickr account before you can use them.
