sWPV ("Simple Web Picture Viewer").
Once setup, you just copy your original pictures to a new folder with an FTP client, and the pictures can be watched as a new gallery on the web (or your intranet).
The Java Applet AWT Picture Browser allows anyone to setup and maintain an online gallery of images using no server scripting, and no JavaScript. The JPEG images are transferred to the server as folders of *.jpg files.
