#### Script Output

Similar to the **custom** module, output values of the script is **newline** separated.
The following is the output format:

```
$path\n$tooltip
```

#### Examples:

```
"image#album-art": {
	"path": "/tmp/mpd_art",
	"size": 32,
	"interval": 5,
	"on-click": "mpc toggle"
}
```
#### Example with exec
```
"image/album-art": {
     "exec":"~/.config/waybar/custom/spotify/album_art.sh",
     "size": 32,
     "interval": 30,  
}
```
#### Script album_art.sh
```
#!/bin/bash
album_art=$(playerctl -p spotify metadata mpris:artUrl)
if [[ -z $album_art ]] 
then
   # spotify is dead, we should die too.
   exit
fi
curl -s  "${album_art}" --output "/tmp/cover.jpeg"
echo "/tmp/cover.jpeg"
```
