I found Flickr to be very interesting. I have never considered storing my photos on a server, but I can see where it could be a form of insurance. Putting the photos in sets and tagging them whould also make it much easier to find photos, but it would also take a lot of time to set it all up. I did a little exploring and found some interesting photos. There were some beautiful leaf photos tagged leaf lines by Omni. The picture at the top is one of these,but apparently i still need to figure out exactly how to download it properly. If you click on the box, it will take you to the picture on the Flickr site.
