Hello,
I got a problem with my template node. in this node I load a Picture in the Dashboard.
Now I want the picture to change when the payload changes too. Unfortunately I have no idea how to do this.

If you want to render an html element based on some `msg.payload` data, you can use a `ui_template` node. For instance, assuming you can have a relative url string in your payload, you can insert it into an `![]()
` src attribute using this syntax:
```auto
```
Every time a new payload arrives, the image src is updated, and the new image appears on the dashboard (or a broken image icon, if the url is not valid).
