I have a problem with inserting an image (logo) in the email send to the submitter.
It should be the full url (https://www.dieetcompleet.nl/image/headers/.....)
But if I do and save the form, the short url appear (only : image/headers/...)
So the image does not visible in de email.
I found this problem already at your supportpage (may 2020), but there was no answer for this problem.
