We have added your request to
our Features Requests list.
Please note that once you convert the image to RGB, it will loose some of its color information. Then if you convert the image back to CMYK, it will not be the same as the original. Therefore the existing functionality should be changed - a converted RGB copy should be displayed instead of the original image.
For the time being we would suggest you create a new module or control that implements the desired functionality.
All the best,
the Telerik team
