A SIMPLE HTML ROLLOVER IMAGE WITHOUT JAVASCRIPT
Example:

There are many rollover images scripts that are using javascript language . They are usually quite complicated and also occupying more space. Therefore I present a simple and tiny code solution that works very well even without using javascript ( only html ).
Usage:
Simply copy the code below into an editor and then run the page in the browser.
<html>
<head>
<title>A simple rollover mouse </title>
</head>
<body>
<a href="#" onMouseOver="document.Imgs.src='2.gif'" onMouseOut="document.Imgs.src='3.gif'">
<img src="3.gif" name="Imgs" border="0"></a>
</body>
</html>
