/* Explanation of options used with each individual call in the BODY (nothing to edit here):

 * id - This will be the id and class name of a slides division - Not the optional container division.

 * height - This is the height of the slider - the width is set in the style section.

 * speed - This is the speed of the slider (1-9).

 * direction - Use 0 for up, 1 for down.

 * pause - Use 0 for no pause, 1 for pause onmouseover.

 * create functions - Use 0 for no added functions, 1 for additional functions to use with controls. */
