Geograph went live on March 6th 2005 – three years on it has far surpassed all our expectations! Here is a small selection of the 700,000 images – click the picture for a zoomable version.

This mosaic is derived from Three Trees by David Crocker. Tiles drawn from images submitted to Geograph in 2007 – many thanks to the thousands of photographers who made that possible.

Naturally, the above image is available for re-use under a Creative Commons 2.0 by-sa licence!

The mosaic was created with Metapixel and the zoomable version was generated with Zoomify. Suggestions for more celebratory mosaics are welcome!
