The current zoom function takes the image, uses the existing image size as the window to perform the zoom and executes.
For lots of pictures that are relatively square, this works well enough. However, some images are very narrow (for example, ICK 1 20A). When one zooms, the user sees so little width of the image in the zoom that it's not satisfying.
Two possibilities:
allow narrow images to extend further vertically, and thus fit the width of the column available, regardless of how far down one needs to scroll. (This might be too extreme - though allowing users to enact that size would be nice.
On zoom, reconfigure the picture window to use all the width available in the right-hand container.
