This post says some obvious (but good and valid) stuff but doesn't propose a solution. Images almost by definition showcase visual design not other types of design. Images are a incredibly convenient medium to produce and transmit. Nice visual design can be digested and appreciated nearly instantly. Hence image-oriented design showcases are at the center of the zeitguest of app design.
Come up with a low-friction, high-speed way to share other facets of design, like interaction and information hierarchies, and then the macro-discussion will reach further into those areas. Currently the best medium for this is launching a prototype in an app store or web and publishing it around. You can see how this compares to "uploading a png" to understand the downstream effects.
