+If you want to add an image at the top of the article, please provide an image with a resolution of `1200 x 630`. Please note that if the image aspect ratio does not meet `1.91 : 1`, the image will be scaled and cropped.

+Knowing these prerequisites, you can start setting the image's attribute:
```yaml

image:
path: /path/to/image
- width: 1000 # in pixels
- height: 400 # in pixels
alt: image alternative text

```
-Except for `alt`, all other options are necessary, especially the `width` and `height`, which are related to user experience and web page loading performance. The above section "[Size](#size)" also mentions this.
-
Starting from _Chirpy v5.0.0_, the attributes `height` and `width` can be abbreviated: `height` → `h`, `width` → `w`. In addition, the [`img_path`](#image-path) can also be passed to the preview image, that is, when it has been set, the attribute `path` only needs the image file name.
For simple use, you can also just use `image` to define the path.
```yml
