@ -45,7 +45,11 @@ The following properties can be used to customize your link previews:
| `socialDescription` | `description` | Description to be used for preview. | | `socialDescription` | `description` | Description to be used for preview. |
| `socialImage` | `image`, `cover` | Link to preview image. | | `socialImage` | `image`, `cover` | Link to preview image. |
The `socialImage` property should contain a link to an image relative to your base URL. For example, if you have an image `cover.png` in `quartz/static/`, the `socialImage` value could be `"static/cover.png"`. If your image is in `content/assets/`, then the `socialImage` value would become `"assets/cover.png"`. The `socialImage` property should be a link to an image. It can be relative to your base URL, or you can provide a full URL with scheme (HTTP protocol only). For example:
1. If you have an image `cover.png` in `quartz/static/`, the `socialImage` value could be `"static/cover.png"`.
2. If your image is in `content/assets/`, then the `socialImage` value would become `"assets/cover.png"`.
3. If your image is hosted elsewhere, say `https://example.com/cover.png`, then the `socialImage` value should be `"https://example.com/cover.png"`.
