Email editor 2.0: using a token for the image elements
The new image elements are great as they enable to secure the way images are insterted in an email and how the image will be formatted CSS-wise.
But then it is now impossible to set the image using a token. We can only use real images here:

This idea is about having a 4th choice here, that would be a token.
Would be great in conjunction with and this one
