Hi @Studenroth, Brent ,
I tested it in my environment and the result was the same as yours. The "Image_1" column is not showing up in the Quick Parts menu because it is not a supported column type for Quick Parts. Quick Parts only supports text-based column types.
I discussed it with Office engineers and there is a workaround for your reference:
Store the image in SharePoint and sync it locally through OneDrive.
Use the "Picture" content control. Then go to the document, on the Developer tab, in the Controls group, selcet picture content control.
Select From a file to insert a picture.
Hope this is help.
