    <p>I am struggling with my custom Javascript / Jquery code.</p> <p>My code currently takes foldername, imagename, url dynamically from a PHP variable and passed to a function <code>slideShow()</code>.</p> <p>The following code works but shows a blank screen at the start and after the first cycle of images is completed. I understand that if all the images need to be loaded before they can be displayed, there will be a slight delay. Watch the cycle of the images, after cycling 7-8 times, the pages goes blank for 5 seconds before displaying again.</p> <p>Working copy of the page is here <a href="http://tinyurl.com/8yqwvqs" rel="nofollow">http://tinyurl.com/8yqwvqs</a></p> <pre><code> &lt;script type="text/javascript"&gt;

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.
