Add attachment =True , it should work

Hi,

In default odoo you can not define many2one field with field name "name" with image field in a same form view because it generate error in addons to avoid this situation follow odoo name field rules.

Regards

As I can see in your code your related field is point to name and it should be related to name_id

image_id = fields.Image(related='name_id.image_1920')

I have tested it in sale order and its working. I have added the below field in sale order:

image_1920 = fields.Image(related='partner_id.image_1920')

<xpath expr="//div[hasclass('oe_title')]"  position="before">
        <field name="image_1920" widget="image" class="oe_avatar" options="{&quot;zoom&quot;: true}"/>
</xpath>

If its not work, to add compute_sudo= True to the field.
