    <p>Okay, so like any programming task you want to break something like this down into simple steps. In this case, maybe something like this:</p> <ol> <li>When the page loads, only show the first image. To do this, you should have a <code>display:none</code> CSS rule on all of the images EXCEPT for the first one. This can easily be accomplished by created a class called <code>hide</code> and applying it to the HTML. We could also manage this via JS, but that may cause bugs depending on the internet connection that your users have...</li> <li>Every five seconds, fade the current image out, and fade the next one in.</li> <li>If we are on the last image, make sure we go back to the first image in the list.</li> </ol> <p>That's pretty much all we need to do, so let's write some code:</p> <p>First, let's refactor your markup to use an id for the container and then add the CSS class to all images but the first.</p> <pre><code>&lt;div id="img_container"&gt; &lt;img src="images/1.png" class="image_wall_thumbnail" /&gt; &lt;img src="images/2.png" class="hide image_wall_thumbnail" /&gt; &lt;img src="images/3.png" class="hide image_wall_thumbnail" /&gt; &lt;img src="images/4.png" class="hide image_wall_thumbnail" /&gt; &lt;img src="images/5.png" class="hide image_wall_thumbnail" /&gt; &lt;img src="images/6.png" class="hide image_wall_thumbnail" /&gt; &lt;/div&gt; </code></pre> <p>Next, let's write a little CSS:</p> <pre><code>.hide { display:none; } </code></pre> <p>Okay now is the "tricky" part where we write some JS:</p> <pre><code>$(function() { //cache dom elements and set init vars var $img = $('#img_container').find('img'), max = $img.length, //how many images you have in the container current = 0; //we will start the script at the first item //Every five seconds, run the code within the handler setInterval(function(){ $($img[current]).fadeOut('fast', function(){ determineIndex(); //Update the index of the image in the img array $($img[current]).fadeIn(); }); }, 5000); function determineIndex () { current = (current === max - 1) ? 0 : (current + 1); } }); </code></pre> <p>Now here's the demo! <a href="http://jsfiddle.net/T2nzh/" rel="nofollow">http://jsfiddle.net/T2nzh/</a></p> <p>Comment if you have any questions about how the javascript works. :)</p> <p>EDIT: Okay, so if you want to just randomly swap out image sources, check this out. The html you want:</p> <pre><code>&lt;div id="img_container"&gt; &lt;img src="images/1.png" style="background:red" class="image_wall_thumbnail" /&gt; &lt;img src="images/2.png" style="background:silver" class="image_wall_thumbnail" /&gt; &lt;img src="images/3.png" style="background:purple" class="image_wall_thumbnail" /&gt; &lt;img src="images/4.png" style="background:yellow" class="image_wall_thumbnail" /&gt; &lt;img src="images/5.png" style="background:green" class="image_wall_thumbnail" /&gt; &lt;img src="images/6.png" style="background:blue" class="image_wall_thumbnail" /&gt; &lt;/div&gt; &lt;div id="img_spares" style="display:none;"&gt; &lt;img src="images/7.png" style="background:magenta" class="image_wall_thumbnail" /&gt; &lt;img src="images/8.png" style="background:brown" class="image_wall_thumbnail" /&gt; &lt;/div&gt; </code></pre> <p>And the JS:</p> <pre><code>$(function() { //cache dom elements and set init vars var $img = $('#img_container'), $spares = $('#img_spares'), max = $img.find('img').length, spares_max = $spares.find('img').length; //Every five seconds, run the code within the handler setInterval(function(){ $($img.find('img')[randomIndex(0,max)]).fadeOut('fast', function(){ var $el = $(this), el_source = $el.attr('style'), $swap = $($spares.find('img')[randomIndex(0,spares_max)]), swap_source = $swap.attr('style'); $el.attr('style', swap_source).fadeIn(); $swap.attr('style', el_source); }); }, 1000); function randomIndex (min, max) { return Math.floor(Math.random() * (max - min + 1)) + min; } }); </code></pre> <p>And the demo: <a href="http://jsfiddle.net/T2nzh/3/" rel="nofollow">http://jsfiddle.net/T2nzh/3/</a></p>

    2. COThanks a lot Matthew! I really appreciate the help. I have a question about the max variable. In the comment you ask how many images you have in the container, should I actually replace ".image" with the number or a variable that has the amount? And in the fiddle it seems it only shows the red box and fades out for a long while then shows again rather than all the other colored boxes showing. Thanks!

    3. COThe `max` variable automatically determines the number of images that you put in the container. So I set this up so that it goes one by one through each of the images, as opposed to a random order. All you'd have to do to randomize it would be to edit the `determineIndex()` function. Now, if you want to have all images display at once and then replace one at random, you'll need a slightly different approach.

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.
