We have a similar use case where we need field staff to take some photos and add them to a form, complete other relevant fields, and then have the form emailed to the email address that is one of the fields in the form.
Right now we are doing this, and more, by using a custom html form that sits on another site. We create a pdf of the completed form, including the attached images, email the pdf to the email address that was included in the email field on the form, then use Integromat to transfer the data to a monday board, and add attachments as an update against the newly created item.
Once it is set up, it works ok. We are even creating dropdown fields on the form from data (items) that are contained on other boards in monday; which is really powerful. But it takes a lot of time to set up.
If we could use either the Outlook or Gmail integration to email the photos that are attached to a monday form, it would save us many hours of work.
