The image function in the statement "im = image(your-image_array)" will open a window on your screen. The variable "im" is the corresponding IDL graphics object.
Changing any of its property (like MIN_VALUE) will dynamically change the display. For instance, doing im.MIN_VALUE=-500 will redisplay your image in range [-500,1000], then doing im.MAX_VALUE=500, in range [-500,500].
IDL himself adjusts automatically the 256 available grayscale levels behind the scene.
