A while back there was a link up on Sea Breeze to a site where you could see satellite images for a particular spot over time. It may have been Google Earth related, but it wasn't the 'historical images' you can select using the time-slider within Google Earth. Can anyone remember the link? I think Johno may have posted it, or reposted it from another forum?

Here is your post Dave from page 23 I think this is what your looking for. Oops Barry beat me to it
