Just to be clear  … the [NSBundle-pathForImageResource:] is from a category in 
the gui library, and is theme-aware, but the [NSBundle-pathForResource:ofType:] 
methoid is from the base library and not theme-aware.
So a theme aware app needs to use -pathForImageResource: to load its own 
images, but if it does so, it should get the image the theme defines for the 
bundle (as determined by the bundle identifier).
