Over the last 10 years I have worked with 4 digits worth of people. Managers, sales people, engineers, family members, locals, Western foreigners, Arab foreigners, Asian foreigners. I can't remember a single communication where direct insertion of images was a desired feature. If at all images were in emails because the email clients interpreted adding attachments in image format as part of the emails content (gmail client for instance).
I'd argue that images in emails means that you haven't reached 2017 yet, where there are loads of better options to share images.
