Hi,
I create my picture
    myPict = [[NSImage alloc] init...
Then many other objects use this picture.
    [rectangle usePicture:myPict];
    [circle usePicture:myPict];
When the user changes the picture I have to update the picture in all the objects. Instead I would like to use pointers and avoid to relink all the objects to the new picture all the time.

Make the picture a property of some centralized object, or a singleton in its own right, and reference that object from within your other classes instead of trying to cache the NSImage explicitly.
