This script automatically determines whether your GD Library supports GIF or JPEG images. The thumbnails are directly output to the browser in extra frames. The advantage of this method is that no temporary pictures are needed, the downside is that the pictures themselves can't link to the big images and your browser needs to support frames. This script also works if your picture's file names contain special characters. The data entered at the configuration site is saved in an external configuration file. The script also features a navigation bar on the left which shows the directory structure of the server and lets you select directories with pictures which will be displayed. The navigation can be hidden. Needs Apache Webserver installed to work.
