Images submitted could not be displayed in admin page

I’ve built two separate page, one for the user to upload

his picture, and the other for the admin to verify this picture. But when the picture is uploaded by the user, it is not displayed in the admin page.
PS: The data fields and data sources in the reaping group and picture uploader group I believe they’re correctly set up. I don’t know if there is something to fix in the workflow or it has to do with admin access setup. Please help me guys, I’ve been wrestling with this issue for over a week now.

Have you tried using the debug mode and inspecting that element to see what values or data it shows?

I’m not sure on how to do that. But here are some new insights that popped up when I ran the inspector.

the only problem is that
the image can’t be loaded in the admin page.
