This post covers the **imghover and img shortcodes**. Images can also be embedded directly using markdown ``, but it is better to use a shortcode so you can explicitly set the width and height, this will help prevent content layout shift which improves user experience and the google lighthouse score.

# img Shortcode
- src is the path and filename of the image. (mandatory)
- class sets a class for the image. (optional)
- alt sets the alt note for the image. (recommended for google lighthouse)
- w is the width of the image. (recommended for google lighthouse)
- h is the height of the image. (recommended for google lighthouse)
## Usage (same path)
```rs
{{/* img(src="ferris-happy.svg" alt="Ferris is Happy" w=600 h=400) */}}
```
**Output**
```html
{{ img(src="ferris-happy.svg" alt="Ferris is Happy" w=600 h=400) }}
```
{{ img(src="ferris-happy.svg" alt="Ferris is Happy" w=600 h=400) }}
## Usage (relative path ./)
```rs
{{/* img(src="./img/ferris-gesture.svg" alt="Ferris says Hello" w=600 h=400) */}}
```
**Output**
```html
{{ img(src="./img/ferris-gesture.svg" alt="Ferris says Hello" w=600 h=400) }}
```
{{ img(src="./img/ferris-gesture.svg" alt="Ferris says Hello" w=600 h=400) }}
## Usage (root path /)
```rs
{{/* img(src="/overview-rich-content/ferris.svg" alt="Ferris the Rustacean" w=600 h=400) */}}
```
**Output**
```html
{{ img(src="/overview-rich-content/ferris.svg" alt="Ferris the Rustacean" w=600 h=400) }}
```
{{ img(src="/overview-rich-content/ferris.svg" alt="Ferris the Rustacean" w=600 h=400) }}

# imghover Shortcode
The first image in the src array is the one compared to all the others.
When you hover your mouse over an image it will display the image to compare.
This can be used to compare only one image with another by passing only two src in the array.
- src is an array of paths and filenames for the images. (mandatory)
- w is the width of the image.
- h is the height of the image.
- p is the percent size that you want the image to use on the page. (50 is the default)
*w and h are used only to calculate the aspect ratio, overall size is set by p*
## Usage (same path)
```rs
{{/* imghover(src=["ferris.svg", "ferris-gesture.svg", "ferris-happy.svg"] w=600 h=400 p=45) */}}
```
**Output**
```html
{{ imghover(src=["ferris.svg", "ferris-gesture.svg", "ferris-happy.svg"] w=600 h=400 p=45) }}
```
{{ imghover(src=["ferris.svg", "ferris-gesture.svg", "ferris-happy.svg"] w=600 h=400 p=45) }}
## Usage (relative path ./)
```rs
{{/* imghover(src=["./img/ferris.svg", "./img/ferris-gesture.svg"] w=600 h=400 p=45) */}}
```
**Output**
```html
{{ imghover(src=["./img/ferris.svg", "./img/ferris-gesture.svg"] w=600 h=400 p=45) }}
```
{{ imghover(src=["./img/ferris.svg", "./img/ferris-gesture.svg"] w=600 h=400 p=45) }}
## Usage (root path /)
```rs
{{/* imghover(src=["/overview-rich-content/ferris.svg", "/overview-rich-content/ferris-gesture.svg"] w=600 h=400 p=45) */}}
```
**Output**
```html
{{ imghover(src=["/overview-rich-content/ferris.svg", "/overview-rich-content/ferris-gesture.svg"] w=600 h=400 p=45) }}
```
{{ imghover(src=["/overview-rich-content/ferris.svg", "/overview-rich-content/ferris-gesture.svg"] w=600 h=400 p=45) }}
