i need to view a file or image in a stateless form that was uploaded to a regular form

I am trying to view an image or pdf file that I have loaded into a different form in a stateless form.

example:
I load a doc or image into Form1 but I want to fetch it and view it in StatelessForm1
How do I do this?
