Odoo does not natively support the inclusion of images in error pop-ups. However, you can achieve this by customizing Odoo’s behavior. Here are a couple of alternatives you might consider:

1. Custom Pop-up or Wizard: You can create a custom pop-up or wizard that includes the image and the necessary instructions. This would require some development expertise in Odoo’s framework.
   
2. Custom Field: Another option could be to add a custom field on the form view that displays the image and instructions. This field could be made visible only when certain conditions are met.
3. Website Page: You could create a website page with the guide and instructions, and then provide a link to this page in the error message. This way, users can refer to the guide whenever they encounter the error.
