I've added this image from Flickr because in about two weeks this is where I'll be. My best friend is getting married in Malaga, Spain and I can't wait. It looks gorgeous!
On a more work-related note, Flickr is a wonderful tool. If a patron ever needs a random photograph of a place/object this would be much better than Google Image, which is what I've used in the past. The third party app that I enjoyed was the Flickr Color Pickr. Not necessarily useful to me, but really fun.
