Retrieve Enumeration image in JavaScript

I require some advice on retrieving the image associated with an enumeration via javascript

The relevant obfuscated code from mxclient.js may be the following:

                        switch (_799.render.toLowerCase()) {
                            case "icon":
                            case "enumicon":
                                var src = _799.display.mapping[_79a.get2(_79b)];
                                _79c = src ? "<img src='" + _787.getStaticResourceUrlFromPath(src) + "'>" : "";

                        switch (_799.render.toLowerCase()) {
                            case "icon":
                            case "enumicon":
                                var src = _799.display.mapping[_79a.get2(_79b)];
                                _79c = src ? "<img src='" + _787.getStaticResourceUrlFromPath(src) + "'>" : "";

Thankyou
