Enterprise 10.9.1 Multiple Photos in Pop-up

[ShaneHertzog10]

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.

@ShaneHertzog10  Did you ever figure this out?  I'm also using Enterprise 10.9.1 and have the same question.
