Currently, when a custom field containing an image is referenced in a Channel Template that is automatically sent to Airbnb guests, only the image URL is delivered in the message body - the image itself is not rendered inline.
It would be very useful to support inline image rendering within Airbnb channel messages (or at minimum, automatically send the image as a photo attachment), so that hosts can share visual content (e.g., property maps, check-in instructions with photos) through automated channel messaging without requiring manual intervention.
