title: Object doesn't support property or method 'removeClass'
body: <p>Im trying to do a simple removeClass and addClass to change styles on an Img.</p>
  
  <pre><code>    &lt;div id="Pic_Viewer"&gt;
          &lt;div id="Main_Pic_Viewer"&gt;
                  &lt;div class="Not_Selected" &gt;
                      &lt;img src='#' alt="PicURL_1" /&gt;
                  &lt;/div&gt;
                  &lt;div class="Not_Selected" &gt;
                      &lt;img src='#' alt="PicURL_2" /&gt;
                  &lt;/div&gt;
          &lt;/div&gt;
          &lt;div id="Small_Pic_Viewer"&gt;
              &lt;ul&gt;
                  &lt;li&gt;
                      &lt;img class="Small_Pic" src'#' alt="PicURL_1" /&gt;
                  &lt;/li&gt;
                  &lt;li&gt;
                      &lt;img class="Small_Pic" src='#' alt="PicURL_2" /&gt;
                  &lt;/li&gt;
              &lt;/ul&gt;
          &lt;/div&gt;
      &lt;/div&gt;
  </code></pre>
  
  <p>I have tried doing this with the #Main_Pic_Viewer img inside div and without.</p>
  
  <p>js:</p>
  
  <pre><code>$('#Small_Pic_Viewer ul li').click(
          function () {
              var ThisLI = this.firstElementChild.alt;
              var BigImgDiv = $('#Main_Pic_Viewer div');
              var CurDiv;
  
              for (var i = 0, l = BigImgDiv.length; i &lt; l; i++) {
                  CurDiv = BigImgDiv[i];
                  if (BigImgDiv[i].children[0].alt === ThisLI) {
                      CurDiv.removeClass('Not_Selected').addClass('Selected');
                  } else {
                      CurDiv.removeClass('Selected');
                  };
              };
          }
      );
  </code></pre>
  
  <p>Not sure why im getting this error message, as removeClass() is working fine in other methods.</p>
