Can an image from the "Capture photo" module be sent as a separate e-mail attachment?
No, this is not possible with the regular means of smapOne; only a link to the captured photo is generated and displayed in the data inbox. The image can then be downloaded if needed.
However, it is possible to use the RESTful API to develop automations that download attached images from the smapOne platform after a data record is submitted and send them via email.
