The information displayed on the left side of the status bar can be replaced
with the output of a user-provided script, which is called by sxiv whenever an
image gets loaded. The path of this script is
.I ~/.sxiv/exec/image-info
and the first argument to this script is the path of the loaded image.

.SH THUMBNAIL CACHING
To enable thumbnail caching, please make sure to create the directory
.I ~/.sxiv/
.I ~/.sxiv/cache/
with write permissions. sxiv will then store all thumbnails inside this
directory, but it will not create this directory by itself. It rather uses the
existance of this directory as an affirmation, that the user wants thumbnails
