<A HREF="#"
OnMouseOver="document.thePlace.src='2.gif';"
OnMouseOut="document.thePlace.src='1.gif';">
<img src ="1.gif" width = "98" height = "53" name="thePlace">
</a>

SAME CODE AS ABOVE WITHOUT SPACING:
<A HREF="#" OnMouseOver="document.thePlace.src='2.gif';" OnMouseOut="document.thePlace.src='1.gif';"><img src ="1.gif" width = "98" height = "53" name="thePlace"></a>
