If you use -initWithContentsOfURL: that shouldn't happen. Alternatively, you could force the image to load and then use +[NSBitmapImageRep representationOfImageRepsInArray:usingType:properties:] to create an NSData from the image's representations and save that to file. Another approach would be to use NSURLConnection to obtain the image data. That should use the URL cache by default. If it doesn't, you can configure it to. That way, you wouldn't have to manage the cache yourself. (You should make sure the host isn't claiming that the image has to be reloaded every time – i.e. can't be cached. Maybe NSImage would use the URL cache already except the host is preventing it.)
