Summary | Make a single uncompressed zip file from all images in a folder and its subfolders, without also including videos. |

I often see a single photo/art gallery with a nested folder structure that Stash treats as multiple galleries.
For example, Stash would look at a structure like this and make galleries of the 6 innermost folders that have pictures:
Cosplayer/
March 2022/
Gwen Stacy/
Cosplay Photoset/
Boudoir Photoset/
Backstage/
Videos/
Marin Kitagawa/
Cosplay Photoset/
Boudoir Photoset/
Backstage/
Videos/
The innermost folder structure is important, but it is not the most natural grouping, and causes related items to get separated in the app.
If you create a zip file of each related gallery, it will preserve the file structure within that zip file and Stash will treat it as a single gallery. But you don’t want to include videos in the zip file as they will not be seen by Stash or CBZ viewers.

Here is a script to make a single uncompressed zip file from all images in a folder and its subfolders, without also including videos.

Updated August 13 to run image identification and zip creation in parallel.
#!/bin/sh -uo pipefail
# make-cbz.sh
# Create a .CBZ file of all the images in a directory.
# Leave non-image files in place.
#
# Example:
# > make-cbz images/
# ...
# Created images.cbz
#
# Example: zip all subdirectories individually
# > make-cbz */
# ...
# Created a.cbz
# Created b.cbz
# Created c.cbz
#
# Example: use a different extension (default .cbz)
# > EXTENSION=zip make-cbz images/
# ...
# Created images.zip
EXTENSION=".${EXTENSION:-cbz}"
