Hi All-

I'm trying to embed a couple of attachments in my pop-up. I'm having trouble finding code samples to do this in 4.12. Anyone have any resources that can help me accomplish this?

My code thus far:

Is something like this what you're looking for?

Thanks Noah Sager - this is uses a URL of a single image for every feature. I had been exploring that approach. Ideally I need a feature attachment that I can embed where the image is different for each feature.

Perhaps pass a function to the popup content? Then the function could call the appropriate image based on the feature attributes.

PopupTemplate | ArcGIS API for JavaScript 4.13 

When the feature is clicked, the feature is passed as an argument to the function and provides access to the feature’s graphic and attributes. Set the outFields property to specify any fields needed for rendering the popup. The function then executes and returns a value to display in the popup template.

Sorry to ask this - I'm very new to JS. Any chance you could give me a piece sample code?
