Yes, you are right about the predominance of Landscape orientation.
The 'long' images are those of 'long' things like bottles of wine etc.
I hadn't realised that many Members post images without 'sizing & scaling' them. I had always done that because of the massive resolution of modern digital pictures.
I also note that another way of posting images is to use the Forums "attach" option which posts them at the O/P's desired size/resolution.
Thanks for your efforts.
