google earth image

To download a higher resolution image more than 1280x1024 i.e. your monitor resolution, it seems that we have to merge several image screenshots. Enabling grid preview will be good as reference when merging is needed.

Perhaps, there ale are tricks at this site below, but I haven't found any.
