A simple but flexible Photo Gallery generator

[somebody else]

This is a simple PHP insert that can be placed in any web page (if the server supports PHP.) It looks into a directory for pictures, then makes a thumbnail index with links to full-size pictures. With a simple HTML file and some basic CSS it generates pages like this. If anyone wants I can post a sample web page and CSS to go along with this.

	<!-- powered by Scott's amazing one-page Gallery_Builder &copy; 2006 -->
	<?php
	echo "\n<!-- begin \"/includes/gallery_builder.php\" -->";
	// The following 5 constant definitions need to be pasted into each gallery page.
	// define ('COLS', 4); // number of columns to display in each row.
	// define ('THUMB', 'thumbnails'); // name of directory where thumbnail images are stored.
	// define ('IMAGE', 'full_size'); // name of directory where full-size images are stored.
	// define ('TN_HEIGHT', 127);
	// define ('TN_WIDTH', 170);
	// $captions = FALSE; // or TRUE, uses image file name.
	// $strip_front = 4; // number of character to strip from front of filename to generate captions.
	// NOTE: thumbnails and full-size images MUST have the EXACT same names.

	if ($dir = @opendir(THUMB)) {
		echo "\n\t<table class=\"proofs\" cellspacing=\"0\">\n";
		$pictures=array();
		readdir($dir); // "./"
		readdir($dir); // "../"
		while (false !== ($imagename =  readdir($dir))) {
			array_push($pictures, "$imagename");
		}
		closedir($dir);
		sort ($pictures);
		$column = 1;	
		echo "\n";
		foreach ($pictures as $image) {
			if ($column == 1) { echo "\t<tr>\n"; }
			$caption = (substr("$image", "$strip_front", -4));
			$caption = (str_replace("_", " ", "$caption"));
			if ($captions) {
				if (!$strip_front) { $strip_front = 4; }
				if (!$caption) {
					echo "\t\t<td><img src=\"" . THUMB . "/$image\" \n\t\t\talt=\"$image\" title=\"$image\" width=\"" . TN_WIDTH . "\" height=\"" . TN_HEIGHT . "\" /><br />$caption</td>\n";
				} else {
					echo "\t\t<td><a href=\"" . IMAGE . "/$image\"><img src=\"" . THUMB . "/$image\" \n\t\t\talt=\"$image\" title=\"$image\" width=\"" . TN_WIDTH . "\" height=\"" . TN_HEIGHT . "\" /></a><br />$caption</td>\n";
				}
			} else {
				if (!$caption) {
					echo "\t\t<td><img src=\"" . THUMB . "/$image\" \n\t\t\talt=\"$image\" title=\"$image\" width=\"" . TN_WIDTH . "\" height=\"" . TN_HEIGHT . "\" /></td>\n";
				} else {
					echo "\t\t<td><a href=\"" . IMAGE . "/$image\"><img src=\"" . THUMB . "/$image\" \n\t\t\talt=\"$image\" title=\"$image\" width=\"" . TN_WIDTH . "\" height=\"" . TN_HEIGHT . "\" /></a></td>\n";
				}
			}
			$column++;
			if ($column > COLS) { $column = 1; echo "\t</tr>\n";
			}
		}
		if ($column != (COLS + 1)) { echo "\t</tr>\n"; }
		echo "\n\t</table>\n";
	} else {
		echo '<h2 style="color: #F00;">We couldn\'t find a folder named "' . THUMB . '"</h2>';
	}
	echo "<!-- end \"/includes/gallery_builder.php\" -->\n";
?>

Feel free to use as you wish.
