Hello,
Does anyone know of an arcade expression that will allow multiple photos to display vertically in a pop-up window? I'm able to display one photo using this expression:
var Part1 = layer URL
var ObjectID = $feature.OBJECTID
var Part2 = "/attachments/"
var AttachID = $feature.attachID
return Part1 + ObjectID + Part2 + AttachID
The end result looks like this:

Your help is greatly appreciated.
