Thumbgen

Pre-generates thumbnails for 'Gnome Files' formerly known as nautilus. This is useful if you have a lot of files which you want to glance over but you have to wait for them to load as you scroll. Supports Python 3.5+ and any Linux distro using Gnome Desktop 3. Thanks to James Henstridge for the original script.

Basic Usage

# generating thumbnails for two directories
thumbgen -d directory1/directory1_1 directory2

# Pulling up the help
thumbgen --help

Command Line Options

short	long	Description
-d	--img_dirs	directories to recursively generate thumbnails seperated by space, eg: "dir1/dir2 dir3" [required]
-w	--workers	no of cpus to use for processing
-i	--only_images	Whether to only look for images to be thumbnailed
-r	--recursive	Whether to recursively look for files
	--help	CLI help

Crash due to large image file

We generate large collage image files for printing.

thumbgen consistently crashes on a directory containing a 24213x14173 pixel 200Mbyte image. All images are valid jpegs and can be opened and viewed using 'feh'

Setup: AMD 4750G / 32GB RAM / 512GB SSD / 50TB NAS / Fedora 37

Error message:
