i'm new to html and am trying to work out why my image isn't rolling over. Can anyone help? thanks

<td height="30" colspan="2" align="left" valign="top" bgcolor="#000000"><div align="left"><a href="INFOa.html" onClick="NewWindow(this.href,'name','617','180','no','no','no');return false" onMouseOut="MM_swapImgRestore()" onMouseOver="MM_swapImage('Image62','','INFOon.gif',1)"><img src="INFOoff.gif" name="Image62" width="42" height="30" border="0"></a></div></td>

<a href="name.html" onmouseover="document.but.src='INFOon.gif'" onmouseout="document.but.src='INFOoff.gif'">
<img src="INFOoff.gif" name="but" width="42" height="30" border="0" alt="info"></a>
