		// log latest greatest creation
		if err := ioutil.WriteFile(filepath.Join(cache_folder, "/latest"), []byte(fmt.Sprintf("%d/%d", width, height)), 0644); err != nil {
			// panic is trapped by Traffic and show us a nice stack trace in the browser
			// a proper error handling should be provided, but in this simple example
			// it's used to remind you to always check for errors
			panic(err)
		}
