I know you *think* this is what you want to do,
but I seriously doubt it is *really* what you want
to do. I would probably use a pointer array (or list,
if you are using IDL 8) to store the images, especially
if they were not all the same size. (If they are
the same size, an array would be my first choice.)

FUNCTION CCFs
files=file_search('*.fits', Count=count)
images = PtrArr(count)
FOR i = 0, count-1 DO BEGIN
images[i] = Ptr_New(mrdfits(files[i],0,h))
ENDFOR
RETURN, images
END

ptr = CCFS()
cgImage, *ptr[3] ; To display the fourth image.

END

Cheers,

David
