I want to be able to enable (or even better enable and disable at will) image previews (thumbnails) in Pantheon Files.

enter image description here

In dconf Editor in org-gnome-desktop-thumbnailers nothing is desabled.

PCManFM and Thunar both have them.

sudo scratch-text-editor /etc/xdg/tumbler/tumbler.rc
At the line # Jpeg thumbnailer, set Disabled=false or Disabled=true to enable or disable jpeg thumbnails.

To enable for png and other image formats, under the line # PixbufThumbnailer in the same file, set Disabled=false.

  • What about pngs and other images? The above only works for jpegs.

    It's the PixbufThumbnailer in the same file, but it disables all together pngs and other image formats, except jpgs and camera raw. Commented Dec 28, 2016 at 11:00

If tumbler is enabled then you should get thumbnails when viewing local folders (try pressing refresh if not - if still not then try restarting the tumblerd process using gnome-system-monitor or the commandline).

There is a dconf setting that turns on thumbnailing of remote folders. If you have a recent version then right clicking on a remote folder background should give you a option to turn this on or off.
