I seem to be having an issue with Selenium clicking on a radio button but from the looks of it, it's not an input radio button but an image to look like a radio button. Any idea how I would click on triggerControl2 which is the top button to turn on Use an external certificate.
<tr>
<th>Certificate options</th>
<td>
<table class="middleAlign">
<tbody><tr>
<td><img id="triggerControl2" name="SSLCertModeImg" value="normal" onclick="this.guiAction();" src="../../../img/radio_off_normal.png" checked="false"></td>
<td>Use an external certificate</td>
</tr>
<tr>
<td><img id="triggerControl4" name="SSLCertModeImg" value="auto" onclick="this.guiAction();" src="../../../img/radio_on_normal.png" checked="true"></td>
<td>Use a self-signed certificate (For test use)</td>
</tr>
</tbody></table>
</td>
</tr>
