jQuery slider redirect the image

Question

I'm using jQuery Blinds Slideshow as image slider. I want to redirect the first sliding image to http://google.com when I click on it. I use a html tag like this:

<div class="slideshow">
   <ul>
      <li><a href="http://google.com"><img src="lemons/1.jpg" alt="lemon" /></a></li>
      <li><img src="lemons/2.jpg" alt="lemon tea" /></li>
   </ul>
</div>

<a href="#" onclick="$('.slideshow').blinds_change(0)">1</a>
<a href="#" onclick="$('.slideshow').blinds_change(1)">2</a>

but it doesn't work.
My question is how can I redirect the first sliding image to google.com when I click on it?
Thanks in advance.

Answer 1

Here is something quick and dirty I cooked up modifying the original jquery-blinds. Put it in a new JS file and call it jquery.blinds-0.9-with-hyperlinks.js or something and include it in place of the current jquery-blinds code.

It should work with the HTML you posted above. It simply checks if any of the images are wrapped in an '' tag and if it is, makes the image redirect to that link on click.
