Released: January 2, 2022
Current Version: "0.0.4"
This plugin uses the
ImageMagick command line utility to reduce the width of Image files while keeping the aspect-ratio.
Mostly for the use with Sony-PRS-Readers as some larger images will slow those down considerably.
(And because I'm doing this on an regular basis, and so -after all - it is worth to get a script up to do the job.)
Disclaimer: Since this plugin will replace the images in your ebook with resized images, you might want to save your ePub or create a checkpoint
before running this plugin.

System requirements
Windows-OS (though, it should be possible to add MacOs and Linux support, but I have no chance to test on these systems)
This plugin requires at least
Sigil 0.9.8. If you uncheck the
Use Bundled Python option, you'll also need to install Python 3.
Installation
1. Select Manage Plugins from the Plugins menu and enable the
Use Bundled Python option, if it isn't already enabled (or greyed out).
2. Click Add Plugin and select
ImgShrinker_v0.0.1.zip. This will install the plugin, which you can select via Plugins >
Edit > ImgShrinker.
3. Download and install
ImageMagick - remember the path to the binary - it has to be set on first run
Settings
To select the new maxWidth, edit
ImgShrinker.json and change the maxWidth value. For example:
To display the folder that contains
ImgShrinker.json select Edit > Preferences > Open Preferences Location. Then double-click
plugins_prefs and
ImgShrinker.
Windows users can also press
WIN+R, paste
%localappdata%\sigil-ebook\sigil\plugins_prefs\ImgShrinker into the Run dialog box and hit Enter.

Thanks to generous help from DOITSU v0.0.4 - incorporating the additions from LostOnTheLine - should work for all Sigil versions >=0.9.8
