How to resize images in Hugo
draft image optimisation
Vegard Skjefstad • How to resize images with Hugo
Initial setup limits images to 640 px width
Create this file: layouts/render-image.html
{{ $image := (.Page.Resources.GetMatch .Destination).Resize "640x" }}
<img src="{{ $image.RelPermalink | safeURL }}" />
Carried out.
The optimisation only works on bundles.
Looked at Page Info then media for the images, and there were hopeful messages about reduced size, so need to disable the change and inspect before and after.
