The second scheme is implemented by using proxy mode. MyImage function is only responsible for creating img elements, proxy function ProxyImage is responsible for setting loading pictures for the picture, and when the picture is really loaded, myImage.setSrc method in myImage is called to set the path of the picture.

I solemnly advise you not to expect any "customs clearance skills"! Flying is no laughing matter. We must be practical and realistic in terms of physical examination. If we can't, we can't!
