This will try to init NSImage with the content of a file that resides in
the current directory (ie. the directory you start the application from)

Because CameraTransfer_header.tiff resides directly in your source
directory, the image will be loaded and NSImage is created.

This works, because -pathForImageResource: looks at what is specified
'under' CameraTransfer_RESOURCE_FILES in your GNUmakefile. The tiff is
copied into YourApplication.app/Resources and the above statement will
load the tiff from there...

A 'shortcut' would be

  NSImage *img = nil;
  img = [NSImage imageNamed: @"CameraTransfer_header.tiff"];

It should not and cannot.
