Load any kind of image in vfb

This is somethingg that Vray VFB does, load any kind of Images directly to vfb and save it in history.

I use it sometimes when a client wants another change after a time and I dont have the VRIMG. Simply I just load the .jpg image to vfb, where I could have an idea where to draw the render region and render again. If I want to preserve the whole image, I save it in history, reload and render the desired area without doing it in post. Having this in Corona would be very useful too.
