- Use `get_url` function to generate correct image paths
- Retrieve image dimensions with `get_image_metadata` function
- Update shortcodes: dimmable_image, dual_theme_image, and invertible_image
These changes reduce layout shifts.
Reduces contrast and brightness of images when the dark theme is active.
Useful when invertable-image is not appropriate (photographs, paintings,
colour drawings…)
Useful to invert diagrams, graphs, etc. in dark theme.
To use it in a markdown file, add a line like:
{{ invertable_image(src="/img.png", alt="alt text") }}
