Gliding at Upavon: Two PhotoOverlays

A shot of Upavon and my left knee from the cockpit of a DG1000 glider operated by the Wyvern Gliding Club.

I've compared two methods of embedding this image in a PhotoOverlay. The first kml file simply references the original photo. The second version references an ImagePyramid created from the photo.

The resolution of the image in the first method never equals that of the original photo, and appears blurred as you zoom in. The ImagePyramid version maintains high resolution as you'd expect. The odd thing is that you can zoom in on the plain, blurry image as far as you like, but the ImagePyramid version limits the amount of zoom you can achieve.
