        Hi Eugene,

        This project didn't start with the intent of providing access to reset/update/delete images. To serve all users, there are caches at multiple levels involved (edge, processing, backplanes, requesters). The difficulty is that not all of these caches are capable of reliable removing single entries, and the freshness is also varying wildly (based on effort to recreate, the number of requests, etc, etc).

        However, the feature as proposed is still on the roadmap, and will probably be implemented in the next code-refresh. When this will be finished is uncertain, as many new features and changes are to be incorporated in such an update.

        In the meanwhile, you could consider using our code to set up your own solution. The GitHub-repo is sans any cache, so you should extent it with your own caching solution, or disregard it completly. For starters I would advise some form of reverse caching proxy (like nginx).

              We will reconsider to implement this like Nick suggested. I don't know how many changes there are needed in different parts of the proxy to make this work flawless.

              Please use the onerror event on an img-tag ( http://www.w3schools.com/jsref/event_img_onerror.asp ), I cannot keep track of all requested images, nor serve default images on an 404-error, this would change default behaviour of the proxy on which third-party's rely.

              See:
