Image download extension problem

I have a problem when I want to upload my image. I can see it in my form, but when I try to download it, it gives me the path of the image. Without the image being recognized as an image.

Domain :

<binary name="photo" image="true"/>

View grid :

<field name="photo"/>

viewer :


name file download :

com.axelor.apps.test.db._test_photo_42 (type : com.axelor.apps.test.db._test_photo_42 )

Viewer in view form :


So it displays fine in the form view, but in the grid view I can’t download it. Any idea please?
Thanks for your help.

For grid, adding widget="Image" in the concerned field should be better

Thanks i look this.
