## Markdown

A Markdown image has three components: the image description, the image destination, and optionally the image title.

```text
![white kitten](/images/kitten.jpg "A kitten!")
  ------------  ------------------  ---------
  description      destination        title
```

These components are passed into the render hook [context](g) as shown below.

## Context

Image render hook templates receive the following context:

###### Attributes

(`map`) The [Markdown attributes], available if you configure your site as follows:

[Markdown attributes]: /content-management/markdown-attributes/

{{< code-toggle file=hugo >}}
[markup.goldmark.parser]
wrapStandAloneImageWithinParagraph = false
[markup.goldmark.parser.attribute]
block = true
{{< /code-toggle >}}

###### Destination

(`string`) The image destination.

###### IsBlock

(`bool`) Returns true if a standalone image is not wrapped within a paragraph element.

###### Ordinal

(`int`) The zero-based ordinal of the image on the page.

###### Page

(`page`) A reference to the current page.

###### PageInner

{{< new-in 0.125.0 >}}

(`page`) A reference to a page nested via the [`RenderShortcodes`] method. [See details](#pageinner-details).

[`RenderShortcodes`]: /methods/page/rendershortcodes

###### PlainText

(`string`) The image description as plain text.

###### Text

(`template.HTML`) The image description.

###### Title

(`string`) The image title.

## Examples

{{% note %}}
With inline elements such as images and links, remove leading and trailing whitespace using the `{{‑ ‑}}` delimiter notation to prevent whitespace between adjacent inline elements and text.
{{% /note %}}

In its default configuration, Hugo renders Markdown images according to the [CommonMark specification]. To create a render hook that does the same thing:

[CommonMark specification]: https://spec.commonmark.org/current/

{{< code file=layouts/_default/_markup/render-image.html copy=true >}}
<img src="{{ .Destination | safeURL }}"
  {{- with .PlainText }} alt="{{ . }}"{{ end -}}
  {{- with .Title }} title="{{ . }}"{{ end -}}
>
{{- /* chomp trailing newline */ -}}
{{< /code >}}

To render standalone images within `figure` elements:

{{< code file=layouts/_default/_markup/render-image.html copy=true >}}
{{- if .IsBlock -}}
  <figure>
    <img src="{{ .Destination | safeURL }}"
      {{- with .PlainText }} alt="{{ . }}"{{ end -}}
    >
    {{- with .Title }}<figcaption>{{ . }}</figcaption>{{ end -}}
  </figure>
{{- else -}}
  <img src="{{ .Destination | safeURL }}"
    {{- with .PlainText }} alt="{{ . }}"{{ end -}}
    {{- with .Title }} title="{{ . }}"{{ end -}}
  >
{{- end -}}
{{< /code >}}

Note that the above requires the following site configuration:

{{< code-toggle file=hugo >}}
[markup.goldmark.parser]
wrapStandAloneImageWithinParagraph = false
{{< /code-toggle >}}

## Default

{{< new-in 0.123.0 >}}

Hugo includes an [embedded image render hook] to resolve Markdown image destinations. Disabled by default, you can enable it in your site configuration:

[embedded image render hook]: {{% eturl render-image %}}

{{< code-toggle file=hugo >}}
[markup.goldmark.renderHooks.image]
enableDefault = true
{{< /code-toggle >}}

A custom render hook, even when provided by a theme or module, will override the embedded render hook regardless of the configuration setting above.

{{% note %}}
The embedded image render hook is automatically enabled for multilingual single-host sites if [duplication of shared page resources] is disabled. This is the default configuration for multilingual single-host sites.

[duplication of shared page resources]: /getting-started/configuration-markup/#duplicateresourcefiles
{{% /note %}}

The embedded image render hook resolves internal Markdown destinations by looking for a matching [page resource](g), falling back to a matching [global resource](g). Remote destinations are passed through, and the render hook will not throw an error or warning if unable to resolve a destination.

You must place global resources in the `assets` directory. If you have placed your resources in the `static` directory, and you are unable or unwilling to move them, you must mount the `static` directory to the `assets` directory by including both of these entries in your site configuration:

{{< code-toggle file=hugo >}}
[[module.mounts]]
source = 'assets'
target = 'assets'

[[module.mounts]]
source = 'static'
target = 'assets'
{{< /code-toggle >}}

Note that the embedded image render hook does not perform image processing. Its sole purpose is to resolve Markdown image destinations.
