A selection of the images now fly out correctly and the client is happy with the larger images. I am not happy with the awful alignment of the small hotspot images which try as I might are still skewed in relation to the original.
Any suggestions on a better way to align images other than hit-or miss fiddling?
yes, try using the 1.0.8 editor plugin any move the hotspots with it,
and try to change the width/height settings manually in the xml to change
the aspect of the image to get a better fitting,
