Just another idea - why don't you keep just one image for this purpose. When you need to modify the counter you could simply use the old image and paint over the old numerical value with your background color and then draw the new updated numbers in place - no need to create a new copy every time.

I'll try and explain what I am trying to do. My application has a dock icon that is updated to reflect status in the application (it has a graphical count amongst other things).

What I originally was doing was to just retain the image as you suggested. However, I then modify that image by adding a count to it graphically. Then I set the application icon ([NSApp setApplicationIconImage:icon];).

Trouble is that next time I call [NSImage imageNamed:@"Connected"] I have the modifications as well, so numbers get drawn on top of numbers, and that messes up the icon.

So I decided what I really needed to do was make a copy of the [NSImage imageNamed:@"Connected"]. Then I modify that. I set the application icon image. And release the copy.
