I would delete my own images to clear up room on dockerhub, but they dont have an api to remove images. the only way is to manually click the x in the UI. So, in a lot of ways, docker forced us to "abuse" their service and store thousands of images on a free/open source account. I get this change, and it was inevitable. But its still ironic that you cant delete tour own images. The best way to delete your image is to just stop using it and let docker delete it for you in 6 months.
