帮我把图片换成动态的网络图片可以直接访问的

好的，以下是一个封装了天气显示动态图片的JavaScript函数：

function getWeatherIconFromSkycon(skyconCode) {
  switch(skyconCode) {
    case "CLEAR_DAY":
      return "https://s3-us-west-2.amazonaws.com/s.cdpn.io/162656/ClearSkyDay.gif";
    case "CLEAR_NIGHT":
      return "https://s3-us-west-2.amazonaws.com/s.cdpn.io/162656/ClearSkyNight.gif";
    case "PARTLY_CLOUDY_DAY":
      return "https://s3-us-west-2.amazonaws.com/s.cdpn.io/162656/PartlyCloudyDay.gif";
    case "PARTLY_CLOUDY_NIGHT":
      return "https://s3-us-west-2.amazonaws.com/s.cdpn.io/162656/PartlyCloudyNight.gif";
    case "CLOUDY":
      return "https://s3-us-west-2.amazonaws.com/s.cdpn.io/162656/Cloudy.gif";
    case "RAIN":
