            provided to 'transform' an image 'Siemens MRI New version'
            into an image 'Siemens MRI old version'
            If user tries to 'merge' two mismatching images
            e.g. a LUT image and a RGB image
            or a compressed and an uncompressed one
            or a single frame and a multiframe,
            or a '12 Bits Allocated' image and anything else, etc,
