Thumbnail AutoIndex

Thumbnail AutoIndex is a nifty little script that helps generate thumbnail indexes for images in your directories. It works hand in hand with mod_autoindex for Apache, making it super easy to create a visual gallery of your images.

What's New in This Release

This latest version has some cool updates:

• Fixed PHP5 MIME detection


• Improved PHP5 If-Modified-Since handling


• Etag support added


• Fixed script real path detection issues


• A few cosmetic changes for better looks!

Requirements to Get Started

If you want to use this script, here’s what you'll need:

• libGD


• libGD 2: Seriously recommended!


• PHP 4.3+: Make sure you have mod_php setup.


• GD support and mime.magic support.

Your Quick Start Guide

If you're looking for a quick setup, just rename the file thautoindex.php to index.php and place it right alongside your images. Easy peasy!

A Better Approach for Setup

If you want something more organized, you can put thautoindex.php in a folder like /home/http/tools and run this command:

ln -s /home/http/tools/thautoindex.php ~/public_html/gallery/index.php

Subdirectory Support Made Easy!

If you want to manage subdirectories, rename thautoindex.php to index.php, place it in your gallery-root directory, and execute the following commands:

cd gallery/root/dir 

  find * -type d -exec ln -s `pwd`/index.php {}/index.php ; 

User-Changeable Options

You can tweak some settings at the start of the script like font size, $DirectoriesFirst, $OpenNewWin, and $cacheDir options. The $cacheDir can be set up in /tmp or your home directory. You may also change names of $headerfile or $readmefile if needed (but I wouldn’t recommend it).

If there’s a $headerfile (default 'HEADER.html'), it will show up at the top of your page as a header. And if there's a $readmefile (default 'README.html'), it'll appear at the bottom as comments.

No Complicated Setup Required!

This script is designed to work out-of-the-box with minimal fuss! By default, it's set up to use the server's /tmp directory for caching images. If server-side caching is turned off, it tries using web caches instead. Setting $OpenNewWin to 'true' can also help out.

The Latest Updates Include:

• Additions like subdirectory support and options for thumbnail sizes.


• This release also fixes URL handling issues along with PHP 5 MIME detection and an include() security problem.
