Closed Feature: Feature request: Image selector widget to show an image thumbnail [825]

At the moment if an image is chosen, only image name is visible and there's no friendly way to see which image is actually selected.
Suggested solution: to show a thumbnail. Implementation is pretty straightforward. I attached an example, which took me ~12 min to implement

P.S.: For those who wants to try it, copy the attached file DataReferenceTreeSelector.ashx to
\Composite\controls\FormsControls\FormUiControlTemplates\Selectors
Comments: Implemented
