 ### Added
 
+- Vendor-model photos on asset detail heroes: computers and printers now
+  surface the linked model's `imageurl` in their extension payloads (the
+  field machines already exposed), and the machine, PC, printer, network
+  device, and measuring tool detail pages render the photo in the hero card
+  when present (hidden cleanly when absent). Network devices and measuring
+  tools have no model link yet, so their heroes stay photo-less until one
+  is added.
 - Dualpath "single machine" site toggle (`dualpath_single_machine`, default
   on). A Dualpath relationship pair is one physical dual-bay machine (single
   controller, bay-selector switch); when on, the machines list, dashboard and

+"""Vendor-model photo surfaces in asset-extension detail payloads.

+Machines, computers, and printers link a vendor Model via modelnumberid; when
+that Model carries an imageurl, the extension dict in the GET detail payload
+must expose it as 'imageurl' (the field name machines established, consumed by
+the detail-page heroes and the machine badge). When no model is linked, the
+field must be absent so the frontend v-if renders nothing.
