Eureka! Well Sabine actually. So how is a chance meeting with an East German responsible for me at last being able to upload pictures?

The answer's in the photo. This is half way up a very steep hill- one of many that day- so I stopped to swap pleasantries, and catch my breath, which took a rather circuitous route via the sun and Wiemar Republican Gun dogs to my guess, looking at the size of the camera bag, that she was a photographer, thence to the problem of resolution and the subsequent resolution of my problem by an adjustment to my camera.
