This pic for instance. When you uploaded it you will have seen an option to "describe" the photo and "map this photograph" click that and then it'll bring up a map of the world search for Oamaru and pan around until you can identify the land feature and click the map. Then if the Google Earth administrators agree, the picture will appear in Google Earth at that spot - the club gets the qudos and so does North Otago. You may have to remove that logos.
The "sinkholes" (called Dolines) at Craigmore Station for instance would be agreat photo to have geo-located so people can see the feature both in your pic and in Google earth.
How do you geo-code?
