Anyone know the secret to getting jisql to find the images used for the up, down, and history icons when you are not running jisql in the current directory (UNIX) ?

If i start jisql in the current directory, it finds the images in the images directory. If i'm not in the directory with jisql, it doesn't find the images for the splash screen or the icons. I figure there's an environment variable that will do it, but it haven't see it documented.
