Lefteris,
Thanks for the information. Yes, I have tried various settings of the Force Resize but not the thumbnails as the thumbnails are just fine as they are.
I understand the issues involved with being able to fit the image into a fixed box that is set for the display dimensions. However, I'm sure I am not the only person who has had images that are resized to a dimension where critical details are not easy to see. I don't think there is any desire for the developers to redo the code so that a scroll bar appears for images whose height will not fit into the displayable height. However, I do think there should be a 'default' link of 'every' gallery or maybe on a bar above or below where you can have an option to 'View Full Size Image' which, if clicked, would open the image in a separate window which the user can view using the default click to toggle full-size or resized for the browser display.
Here is the image I would like to have viewable in full size, 800px X 2433px:
