<div align=center> The method of pre-reading images is relatively simple and can be implemented using JavaScript. Place code similar to the following in the <head> area of HTML: <SCRIPT LANGUAGE="JavaScript"> <!-- Image1= new Image(100,50) Image1.src = "image1.gif" Image2 = new Image(100 ,50) Image2.src = "image2.gif" Image3 = new Image(100,50) Image3.src = "image3.gif" // --> </SCRIPT> In this way, the browser has already downloaded it in advance when loading the page. 3 pictures (image1.gif, images2.gif and image3.gif). When the onmouseover event is triggered, the browser reads the image directly from the Cache, which is of course much faster. Here are some small explanations: the name of the picture can be arbitrary, 100 and 50 are the width and height of the picture read into the cache respectively. But the script format must be written in the prescribed format, "Image1=new Image". If the image is in a subdirectory of another server, just use the correct absolute path. </div>
