Monetizing Images With WordPress

Does anyone know of a WordPress plugin that adds a dynamic placeholder for image file URLs? It would be similar to how GiphyCat and Imgur works when you navigate to a .gif or image file (direct path) and there are ads above and/or below the image being served up.

Basically you would be able to directly share your image on a bookmarking site like Reddit and when the user visits the image there would ads on it.
