I set up thumbnails for GIF images on an earlier version of Ubuntu by following the instructions in this answer. Since my upgrade to 17.10 I've noticed GIF thumbnails are no longer generated.

I've walked through those steps again, and ensured that:

  • /usr/share/thumbnailers/gif.thumbnailer exists and has the correct contents.
  • Imagemagick is installed.
  • I've cleared the cache with rm -r ~/.cache/thumbnails
  • Running convert mygif.gif[0] -resize 100x100 thumbnail.png manually works.

What am I forgetting? How do I get thumbnails for GIF images again?

I got gif thumbnails working again by installing the gif-thumbnailer package from the atareo/thumbnailers repository:

sudo add-apt-repository ppa:atareao/thumbnailers
sudo apt-get update
sudo apt install gif-thumbnailer

Then I cleared the thumbnail cache (rm -r ~/.cache/thumbnails) and everything's working.

The source code seems to be in this misnamed git-thumbnailer repository. I haven't entirely figured out why this solution works and the others I've tried do not; it still depends on imagemagick, but passes different options, and copies images to a temporary directory before operating on them. Anyway, that worked for me.
