When user select an image from the image browser, it inserts to the Editor as next:
<img alt="" src="/Learn/ImageBrowser/Image?path=Chrysanthemum_636263051836972436.jpg" />
While adding the image we also can set Alt text, Width, Height.
But how to add class to <img> tag?
Result has to be like: <img class="img-responsive" alt="" src="/Learn/ImageBrowser/Image?path=Chrysanthemum_636263051836972436.jpg" />
