No. You can do it through the js effect. The onmouseover event is generated when the mouse moves to the image. Programming in the event. Change the address of the image. Will achieve the effect you want.

example

& ltImg src="a.gif" alt= "Nanchang infertility network" onmousemove = "this.src =' b.gif'"/>

This way. When the mouse moves. A.gif became b.gif.
