Thank you for answering my “noobish” question.

Best Solution And Answer

Do something like this:

NSBitmapImageRep *imgRep = [[image representations] objectAtIndex: 0];
NSData *data = [imgRep representationUsingType: NSPNGFileType properties: nil];
[data writeToFile: @"/path/to/file.png" atomically: NO];
