My previous selection of photos on this site was getting somewhat random and meaningless so I've started using Flickr - "almost certainly the best online photo management and sharing application in the world". It really does have a lot of good features for organizing, describing, grouping and editing photos, including this groovy little flash panel that displays my latest pics.
