Size of Flash movie and posititions of interface elements
The default configuration of exposť defines the Flash movie as 900 pixels wide by 510 pixels high, which makes it suitable for images up to 400 pixels tall. You can change the movie size by opening expose.html in an HTML editor. Then change the width and height parameters in the object and embed elements.
After you resize the Flash movie, open config.xml which is located in the config subfolder inside the expose folder. This file contains several parameters for the vertical position of the main panel, the image, the image strip, etc. Edit their values to reposition these interface elements.
