Cropped vs resized thumbnails (previews)

[rsholmes]

Version (please complete the following information):

• OS: Linux Mint
• Version 21.2
• Package deb

Describe the bug
Thumbnails are inconsistent: Some are full images, reduced in size, showing image file name; some are cropped, not showing file name. Cropping appears to be to lower left part of image, sometimes omitting the main subject in the center. Cropped images are a good width, but butt up against images above and below with no separation. Uncropped image thumbnails are too small, not using full width of preview pane.

To Reproduce
Steps to reproduce the behavior:

1. Just view a directory

(My preference would be to always see the full image reduced as thumbnail, with file name shown, using the full width of the previews pane, separated from images above and below.)
