Thank you so much for your responsiveness, especially considering how busy you are with priority work. Another dumb question, what constitutes subscription-based sources? If I have digital subscriptions through the Wall Street Journal, New York times, and Washington post, am I permitted to embed their stories in any image format?
Lastly, just a suggestion as this appears to be a major problem: Why not just require writers to use one header image per the main criteria on Medium via Illumination? This might simplify the process, as less is more. Just some food for thought.
