If you enjoy figuring out the ID of plant photos, there is a collection of over 5,000 photos which need help being labeled. They are all free-use photos, that can be used by anyone in the world, where ever they like, and thousands more will be added soon. You can add your own photos as well to the collection. http://www.gardenology.org/wiki/Iplantification If you look a photo or two past a plant photo, there may be a photo of a label identifying the plant - though that is often not the case, and they can be wrong... thus the need for plant ID experts.
