/*

These scripts enable an automated sequential
slideshow by adding a timed auto-advance feature
to the standard javascript image slideshow

The auto-slideshow also adds a DOM enabled dynamic
label to the basic image swap method. 

Note that the label function will fail/break
in non-DOM compliant browsers. However, the
image swap portion of the script will continue
to function in NS 2+/IE 3+ browsers
