I cannot believe that, after all this time, you can’t come up with a workaround. Every other email I receive through my Outlook account either comes with an image or the ability to download one. Instead, with NB, I have a big blank space where all of my images — including the organization’s logo! — should be. Shrugging your shoulders and essentially saying “too bad” is not helpful in any regard — what would be helpful are instructions, for ALL your clients, on how to at least ensure that your images can be downloaded by the recipient.
