[Wtr-general] How To Click On The Image Button...With This html Code?

[san]

Hi People..

Heres The Code: 

<tr ><td height="15"></td></tr>
	<tr align="left">

	<td align="left" colspan="2" valign=bottom >
	<input border="0" alt="Search" src="../images/search_top.gif" name="CTL_SUBMIT" type="image">
	<a href="FilingsSearch.asp"><img border="0"  alt="Clear" src="../images/clear_search_top.gif"></a>
	<a href="javascript:SaveAlertSearch();"><img border="0"  alt="Clear" src="../images/save_search_button.gif"></a>
	
	</td>
	</tr>

& I Wanna Click On The image button with url "search_top.gif"
So I Used [i]ie.image(:src, /search_top/i).click[/i]
But It Didn't Work Properly As It Always Clicking On The 2nd Occurrence Of "search_top", i.e On The Link "clear_search_top" ... I Don't Know Why...

Any Ideas Will Be Helpful... :)
Thanks....
