As far as I can tell, it is not possible to delete uploaded images and DALL-E 2 outputs through the web app. Since we own the full rights to both of these, we should be able to manually request deletions until this functionality is implemented. To which address should I direct such requests?
I should add that I have seen a couple of other posts regarding the same topic, and it is concerning that nobody from OpenAI has responded to any of them in almost two months.
