<HTML> <HEAD> <TITLE>My Photo Gallery</TITLE> </HEAD> <BODY> <H1>My Photo Gallery!</H1> <?php // $search_dir needs to be relative to the directory where this file is // if the photo subdir exists in this directory, just make $search_dir = "./photo"; // if gallery.php is in /gallery and photos are in /photos, make $search_dir = "../photo"; $search_dir = "./photos"; $files = directoryToArray($search_dir, false); // All files in directory into array ?> <?php // The loop that determines what to do with all the filenames foreach ($files as $num => $filename) { //Make sure it's a .jpg file if (preg_match("/\.jpg$/i", $filename)) { echo "<P>\n"; echo "<img src=\"thumb.php?file=".$filename."\" alt=\"".$filename."\"><BR>\n"; echo "<a href=\"".$filename."\">".$filename."</a>\n"; echo "</P>\n"; } } ?> <?php // From: http://www.bigbold.com/snippets/posts/show/155#related function directoryToArray($directory, $recursive) { $array_items = array(); if ($handle = opendir($directory)) { while (false !== ($file = readdir($handle))) { if ($file != "." && $file != "..") { if (is_dir($directory. "/" . $file)) { if($recursive) { $array_items = array_merge($array_items, directoryToArray($directory. "/" . $file, $recursive)); } $file = $directory . "/" . $file; //remove dirs from dir listing by commenting this out $array_items[] = preg_replace("/\/\//si", "/", $file); //remove dirs from dir listing by commenting this out } else { $file = $directory . "/" . $file; $array_items[] = preg_replace("/\/\//si", "/", $file); } } } closedir($handle); } return $array_items; } ?> </BODY> </HTML>

Copy and save the following code as thumb.php in the same folder as gallery.php.

[Download] (right-click -> Save Target As)

<?php // Max Sizes $th_max_width = 250; // Maximum width of the thumbnail $th_max_height = 250; // Maximum height of the thumbnail //------------------- // File $filename = $_GET['file']; // Content type header('Content-type: image/jpeg'); // Get image sizes list($width, $height) = getimagesize($filename); // Resize $ratio = ($width > $height) ? $th_max_width/$width : $th_max_height/$height; $newwidth = round($width * $ratio); $newheight = round($height * $ratio); // Load $thumb = imagecreatetruecolor($newwidth, $newheight); $source = imagecreatefromjpeg($filename); //Resize imagecopyresized($thumb, $source, 0, 0, 0, 0, $newwidth, $newheight, $width, $height); // Output imagejpeg($thumb); ?> <?php exit; ?>

Now, just put JPG files in a subfolder named photos!
