Problem Getting Image in Template Node

[tcontrada]

I looked around the form, but could not get anything to work correctly.

I want to simply display an image in the dashboard template node.

I have my image file in the .node-red\node_modules\node-red-dashboard\dist folder
and I can view the image in the browser at localhost:1880/ui/Alarm_On.png

The code in the Template Node is

<div><img ng-src="http:/localhost:1880/ui/Alarm_On.png"></div>

Why doesn't this display the image?

Thanks...

Are you isomg the template node or ui_template node?

[tcontrada]

UI-template

[zenofmud]

could you provide the flow? Make sure to read this first: How to share code or flow json

[tcontrada]

The flow is an Inject Node to Trigger the ui_template node, the code is in my first post. It's that simple...

[zenofmud]

Instead of:
<div><img ng-src="http:/localhost:1880/ui/Alarm_On.png"></div>
try
<div><img src="http:/localhost:1880/ui/Alarm_On.png"></div>

`

Also, it needs to start http:// not http:/

[tcontrada]

Thanks, I thought I needed the ng-src in there. Also had a type-o on the http://.

Thanks to any help you can give me with this problem.

Have you tried putting a debug node (set to display the Complete msg object) on the output of the file-out node?

Also add a debug node to the stderr output of the exec node.

And add in a catch node connected to another debug node (set to display the Complete msg object) and see what you get

[Bimgo]

Hello thx zenofmud for your reponse
I have put the debug node but onestly i don't now what can i do with this information...

with debug node i can see the information send from each node but i don't see nothing for my image adress.
thanks

[zenofmud]

Post the info from the debug nodes ao we can see what it is.

It's a good idea to give each debug node a name so you can tell which debug is reporting the information.
