Geograph is a concept and open source code for a online website to create a comprehensive collection of photographs capturing every part of given region.
Currently there are three active projects, shown below - including a photograph from each.
Today's Photo of the dayNY4709 : Thunder Storm by Michael Graham
Caught out by a big storm coming up Longsleddale whilst ascending the pass. Lightning was flashing around me and the thunder was deafening. I was glad to reach lower ground.

Das Foto zeigt den Wasserturm in Burg, der sich auf dem Landesgartenschaugelände des Goetheparks in der Nähe der Gleisanlagen der Deutschen Bahn befindet.
Random photo (doesn't have a daily photo)WV4674 : Dixcart Bay and Hogsback Headland by Colin Smith
"Dixcart Bay - best near low tide when the sand is exposed, also the most easily accessible on the island. For shelter, try this one if the wind is northerly". www.sark.co.uk https://en.wikipedia.org/wiki/Sark
Geograph Britain and Ireland, also has a slightly simplified site schools.geograph.org.uk intended for use within Schools.
... and a sub-project just focusing on images in Ireland, www.geograph.ie.
Geograph Germany/Deutschland, also has a German/Deutsch language version at geo.hlipp.de.
