    <p>I have the following code that is functional that will randomize the photos I have in my 'photos' folder each time the refresh button is clicked. I know this may not be the most efficient way for this to be coded but for my matter it works. I am looking for help regarding my PHP code that will make the photos more random. I currently have 200+ pictures in the folder and often get repeated pictures more than I'd like. What changes to it can I make? (PS. ignore the AJAX/JavaScript I was playing around with)</p> <pre><code>&lt;html&gt; &lt;head&gt; &lt;title&gt;Pictures!&lt;/title&gt; &lt;style type="text/css"&gt; body{ background-color:D3DFDE; } &lt;/style&gt; &lt;script type="text/javascript" src="http://ajax.googleapis.com/ajax/libs/jquery/1.5/jquery.min.js"&gt;&lt;/script&gt; &lt;/head&gt; &lt;body&gt; &lt;div id='main'&gt; &lt;?php function randomimages(){ $dirname = isset($_REQUEST['dir'])? $_REQUEST['dir'] : './photos/'; $numimages = isset($_REQUEST['num'])? $_REQUEST['num'] : 1; $pattern = '#\.(jpg|jpeg|png|gif|bmp)$#i'; $files = array(); if($handle = opendir($dirname)){ while(($file = readdir($handle)) !== false){ if(preg_match($pattern, $file)){ array_push($files, "&lt;center&gt;&lt;img src='" . $dirname . $file . "' alt='' /&gt;&lt;/br&gt;&lt;br/&gt;&lt;hr/&gt;&lt;/center&gt;"); } } closedir($handle); shuffle($files); } return implode("&lt;center&gt;&lt;br/&gt;", array_slice($files, 0, $numimages)) . "&lt;br/&gt; &lt;/center&gt;"; } ?&gt; &lt;!-- &lt;center&gt;&lt;a id="myButton" href="#"&gt;MAS PICTURES!&lt;/a&gt;&lt;/center&gt; --&gt; &lt;center&gt;&lt;input type='button' onClick='window.location.reload(true)' value='MAS PICTURES!!!' style="height:200px; width:150px" /&gt;&lt;/center&gt; &lt;hr/&gt; &lt;script type="text/javascript"&gt; $(function() { $("#myButton").click(function() { $("#main").load("index.php"); }); }); &lt;/script&gt; &lt;?php echo randomimages(); ?&gt; &lt;center&gt;Created by: Matt &amp; Joe&lt;/center&gt; &lt;/div&gt; &lt;/body&gt; &lt;/html&gt; </code></pre>

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.
