    copied!<p>I am creating a slideshow using nested li's:</p> <pre><code>&lt;ul id="ss_images_set"&gt; &lt;li&gt; &lt;img link="images/koala_1.jpg" /&gt; &lt;p class="img_caption"&gt;&amp;#169;Copyright&lt;/p&gt; &lt;p class="img_author"&gt;John Merriam&lt;/p&gt; &lt;p class="img_href"&gt;http://www.twitter.com&lt;/p&gt; &lt;p class="img_hashtag"&gt;JohnMerriam&lt;/p&gt; &lt;/li&gt; </code></pre> <p>I will be uploading new images daily to this slideshow, so there will be many images in the set (hundreds). There are so many pre-loaders out there that I am confused as to what to use to load only the next image. The slideshow has an image pre-loader, but I don't think it works properly because the next images are clearly not cached (content below slideshow jumps up and down when going to next image).</p> <p>Here is the pre-loader script:</p> <pre><code>function preload_images(){ var pre_image = curr_img - 1; if(pre_image &lt; 0) pre_image = (tot_elements-1); var curr_obj = 0; if(!$('#img_preloaded_'+pre_image).length &gt; 0){ curr_obj = slideshow[pre_image]; $('body').append('&lt;img src="'+curr_obj["img_url"]+'" id="img_preloaded_'+pre_image+'" class="preload_box" /&gt;'); } var pre_image = curr_img + 1; if(tot_elements==pre_image) pre_image = 0; if(!$('#img_preloaded_'+pre_image).length &gt; 0){ curr_obj = slideshow[pre_image]; $('body').append('&lt;img src="'+curr_obj["img_url"]+'" id="img_preloaded_'+pre_image+'" class="preload_box" /&gt;'); } </code></pre> <p>I don't know why it's not caching. Is it written wrong? Is it in the wrong spot in the following fiddle?</p> <p>Fiddle with JS: <a href="http://jsfiddle.net/doobada/9m9eq/" rel="nofollow">http://jsfiddle.net/doobada/9m9eq/</a></p> <p>Current ex. of slideshow (content below jumps up and down): <a href="https://www.assembla.com/code/cfrepo/subversion/node/blob/trunk/index.html#image=JohnMerriam" rel="nofollow">https://www.assembla.com/code/cfrepo/subversion/node/blob/trunk/index.html#image=JohnMerriam</a></p> <p>Ok, jQuery is not my strong suite (taking the tuts+ courses now), but this shouldn't be taking me 3 weeks to figure out.</p> <p>Thanks for your help.</p>
