Copy a picture from attachment to 'Picturefield' in a SharePoint list

I want to make an facebook with all the staff from a school. We want that the staff upload their own picture by a Form. So I made a Forms with the File upload option. In Power Automate I put that picture in the Attachment field of the list in SharePoint also with other fields like name and department. 

But I can't find how I can publish a miniature of the attachment in my SharePoint list. I have made another field which I can publish as a miniature and that is how I want to present it. See the picture included. The first line in the SharePoint list is how I want to present it (or something like that) and which I have made manually. The second line is how it is present because I filled out the Forms and the Power Automate has put the picture in the Attachment field.

I hope someone can help me!
