Error in thumbnail generation for tif and dng

[webysther]

After doing this inside the container:

apt-get install -y libtiff6 dcraw

or

environment:
  DOCKER_MODS: linuxserver/mods:universal-package-install
  INSTALL_PACKAGES: libtiff6|dcraw

It's now working tif image thumbnail generation.

I got the same error when I tried to upload tiff files.
The logs looked like this:
[Nest] 630 - 04/24/2026, 12:00:00 AM ERROR [Microservices:{"id":"cd451b48-5083-40d0-9647-21e294015608"}] Unable to run job handler (AssetGenerateThumbnails): Error: Input file contains unsupported image format

After I run apt-get install -y libtiff6 dcraw it worked perfectly and I got no errors anymore 👍

Thanks! 💯
