Leveraging this jQuery code across multiple div elements

As a newcomer to jQuery, I am currently experimenting with a test script. My goal is to create an effect where when an image is clicked, a div slides down displaying more information similar to the new google images effect.

The issue with the current script is that the div loads open instead of opening on click. Additionally, it only works for one div. Do I need to replicate the script multiple times for multiple divs?

<script src="http://code.jquery.com/jquery-1.9.1.min.js"></script>

<script>
$(document).ready(function() {
     $('#clickme').click(function() {
          $('#me').animate({
               height: 'toggle'
               }, 500
          );
     });
});
</script>


<div id="clickme" style="background-color: #333333; color: #FFFFFF; padding: 10px; width: 200px; cursor:pointer;">
  Click here to toggle me in and out =)
</div>
<img id="me" src="http://www.randomsnippets.com/wp-content/uploads/2011/04/2.png" alt="It&#039;s me....ah!!!" title="Allen Liu" width="100" height="77" class="alignnone size-full wp-image-552" style="border: none;" />

Firstly, it is important to note that using the same ID for multiple elements is not recommended. It is better to use a class instead. jQuery will only recognize the first occurrence of an ID and ignore any additional ones.

Secondly, when working with multiple elements, you need to provide the function with context. For example, use $(this).next(). This helps the browser understand which specific element to target next based on the classes assigned.

$(document).ready(function() {
    // Hide image by default
    $('.me').hide();

    // Specify context for each click event
    $('.clickme').click(function() {
         $(this).next('.me').animate({
              height: 'toggle'
              }, 500
         );
    });
});

HTML:

<div class="clickme" style="background-color: #333333; color: #FFFFFF; padding: 10px; width: 200px; cursor:pointer;">
  Click here to toggle me in and out =)
</div>
<img class="me" src="http://www.randomsnippets.com/wp-content/uploads/2011/04/2.png" alt="It&#039;s me....ah!!!" title="Allen Liu" width="100" height="77" class="alignnone size-full wp-image-552" style="border: none;" />

One way to begin with the div hidden is by setting it to display: none. This can be done through inline styles, a <style> element, or a CSS file.

Using classes and relative positioning, you can achieve your desired effect:

<script>
$(document).ready(function() {
     $('img.clickable').click(function() {
          $(this).prev('.image-info').first().animate({
               height: 'toggle'
               }, 500
          );
     });
});
</script>

<div style="background-color: #333333; color: #FFFFFF; 
      padding: 10px; width: 200px; cursor:pointer; display:none;" 
      class="image-info">
  Information about the clicked image
</div>
<img src="http://www.randomsnippets.com/wp-content/uploads/2011/04/2.png" 
     alt="It&#039;s me....ah!!!" title="Allen Liu" width="100" height="77" 
   class="alignnone size-full wp-image-552 clickable" style="border: none;" />
