Use a UNC path for Image Component in a Expression

I’m trying to get a path from a dataset then use the path for an Image Component.
I need to add file:/// before the properties to get it to work.

How can I prepend this try({Root Container.Image List.data}[{Root Container.Image List.selectedRow}, “Original Image Path”], 0)

with this file:/// ?

Did you mean something like this?:

concat("file:///",try({Root Container.Image List.data}[{Root Container.Image List.selectedRow}, "Original Image Path"], ""))
