## Image shortcodes

### Dual theme images

Useful if you want to use a different image for the light and dark themes:

{{ dual_theme_image(light_src="img/paris_day.webp", dark_src="img/paris_night.webp" alt="The Eiffel tower") }}

#### Usage
```
{{/* dual_theme_image(light_src="img/paris_day.webp", dark_src="img/paris_night.webp" alt="The Eiffel tower") */}}
```

### Invertible image

Good for graphs, line drawings, diagrams… Inverts the colours of the image. The source image will be used for the light theme.

{{ invertible_image(src="img/graph.webp", alt="Invertible graph") }}

#### Usage

```
{{/* invertible_image(src="img/graph.webp", alt="Invertible graph") */}}
```

### Dimmable image

Images with too much brightness or contrast can be jarring against a dark background. Here's an example of a photograph that dims when the dark theme is active.

{{ dimmable_image(src="img/desert_by_oskerwyld.webp", alt="Photograph of a desert, heavenly sky") }}

#### Usage

```
{{/* dimmable_image(src="img/desert_by_oskerwyld.webp", alt="Photograph of a desert, heavenly sky") */}}
```
