We would like to able to display an image in an email template. To position the image in the email template we would like to use a token. The image is stored in a derived entity of system.image. The image is accessible via a 1:1 relation to the entity of the email template. It seems that the requested functionality is not available at the moment. Does anybody know a reasonable workaround?
Maybe encode the image as a base64 string and use it in a html img tag?
