You could use a custom NSValueTransformer.
Subclass NSValueTransformer and have the -transformValue accept one of the objects from your NSArray, and then uses that object to return the appropriate NSImage. Then when you're setting up your bindings, simply type in the name of your NSValueTransformer in the "Value Transformer" field.
