thumbnail access through for loop.

Question

i am creating a photo gallery and am currently stuck on recognizing which thumbnail links to which pic. im using an addEventListener function, kindly suggest the method to go about.

Not entirely sure what you mean here, but let me make a suggestion:

If your thumbnails all link directly to their larger counter-part, you can prevent them from navigating away from the page, and instead bring the larger image in asynchronously:

<ul class="thumbnails">
  <li><a href="bigImg1.jpg"><img src="bigimg1_thumb.jpg" /></a></li>
  <li><a href="bigImg2.jpg"><img src="bigimg2_thumb.jpg" /></a></li>
</ul>

With that markup, we could have the following jQuery:

$(".thumbnails a").click(function(e){
  e.preventDefault(); /* keeps us from actually leaving the page */
  alert($(this).attr("href")); /* tells us the path to our img */
});

Rather than having the alert, you could fade the big image in over the rest of the page, modally.
