I had a good look around the Flickr tools - I couldn't see the point of creating a Librarian trading card, I guess I'm not into playing around for fun. I did discover a good tool to create a jigsaw puzzle from your photos - you can even order to buy a real one created from your photos. I have created one from our holiday in Nelson Lakes late May.

The other tool I was interested in was the Map maker http://bighugelabs.com/flickr/map.php - a good tool to plot the son's overseas trip while I am at home looking at photos and dreaming.
The trip planner http://travel.yahoo.com/trip would be the tool I would use to plan a trip and then post my photos
