Geograph API Demo
Very simple demo of using the geograph API to display thumbnails as part of another site.
View the Source (GPL). This demo simply accepts a location and attempts to convert (using the nearby API) to a lat/long so it can look up photos on Geograph.
Currently understands GB and Ireland Grid References, GB Easting/Northing, UTM References, IARU Locators even UK Postcodes, a Decimal Lat/Long it will also work, as it uses the Nearby API.
