Yes, Ralph, and for feh and llpp.

mpv can be used for images, and its defaults for scaling and exit
(--keep-open=no) seem handy for previewing.

I'd like to use xdg-open as the primary helper, if it's installed on
the system.  It was developed to manage that concern.  Users can
override with their own preferences, of course.

It does seem to use reasonable defaults.  And if a package was
configured to support it, installing or removing it updates the
defaults.

show -preview?  Or, leave this for experienced users to set up
profiles just for preview use.
