Selected image/images as props in component.

[intergalacticspacehighway]

I loved the project and used it in my form to select image but I needed an update form functionality too which is a pretty general scenario, so I had to show pre-selected images, but as the current component functionality doesn't have a feature to pass selected image as a prop, I tweaked the project and implemented it. I have included new examples in demo.js file.
