The website I've built for my photography is completely my own, all the photos, the design, and every scrap of code to make it work. I'm still adding a few features to it, but it's fully functional in its current form.

It uses a little apache magic to redirect all the page requests through either the gallery file or the cache image file, which organize and generate proper size images, respectfully.

[Shift_Photos](http://www.shift.ws/)

Here's the source code.  Some of the formatting is a little broken, but you can get the basic idea.

#### gallery.php

```php
<?php
    function scan($path){
        
        $dir = scandir($path);
        array_shift($dir);
        array_shift($dir);
        sort($dir);
        return $dir;
        
    }
    
    $path = urldecode(dirname($_SERVER[SCRIPT_FILENAME]).$_SERVER[REQUEST_URI]);
    if(!ereg('gallery', $path)) $path .= "gallery/";
    
    if(ereg("jpg", $path)){
        
        $here = scan(dirname($path));
        $current = array_search(basename($path), $here);
        require_once('head.php');
        if($current > 0) echo "<a id='prev' href=\"{$here[$current-1]}\">&lt;</a>";
        if($current+1 < count($here)) echo "<a id='next' href=\"{$here[$current+1]}\">&gt;</a>";
        echo "<img src='/cache{$_SERVER[REQUEST_URI]}/$img?x=710' alt=\"$img\" onLoad=\"javascript:loaded();\"/>";
        echo "<img id='loader' src='/img/ajax-loader.gif' alt='loader' style=\"padding: 50px 0px\"/>";
        require_once('tail.php');
        
    } else {
        
        $here = scan($path);
        
        rsort($here);
        
        $flag = 0;    
        
        foreach($here as $dir){

                $flag = 1;
                $sub = scan($path.$dir);
                rsort($sub);

                    if(ereg("jpg", $img)) break;
                }
                if(ereg("jpg", $img)) echo "<a class='galleryimg' href=\"/gallery/$dir\"><img src=\"/cache/gallery/$dir/$img?x=150&amp;y=150\" alt=\"$img\"/><br/>".ereg_replace("[0-9][0-9] ", "", $dir)."<br/></a>";
                
            }
        }
        
        if(!$flag){
            
        sort($here);
        
        require_once('head.php');
        $page = 1;
        $c = 0;
        echo "<div id='topnav'><div style='padding: 150px;'><img src='/img/ajax-loader.gif' alt='loader'/></div>";
            foreach($here as $img){
                if($c++ % 16 == 0){?>
                    </div>
                    <div id="page<?=$page++?>" style="display:none;">
                <?}
                
                if(ereg("jpg", $img)) {
                    
                    echo "<a class=\"galleryimg\" href=\"{$_SERVER[REQUEST_URI]}/$img\"><img src=\"/cache{$_SERVER[REQUEST_URI]}/$img?x=150&amp;y=150\" alt=\"$img\"/><br/></a>\n";
                    
                }
                
            }
        echo "</div>";
        echo "<div id='nav' style='display:none'><a onclick='javascript:prev()'>&lt;prev</a>&nbsp;";
        for($i=1;$i<$page;$i++){
            echo "<a onclick='javascript:pager($i)'>$i</a>&nbsp;";
        }
        echo "&nbsp;<a onclick='javascript:next()'>next&gt;</a></div>";
