The same slider can appear on multiple pages using just one copy of the slider which is placed on its own page, with the slider page
size matched to the slider size ( height and width). Placeholder’s are used to call that page (as an insert) to any other page with a
simple iframe - the iframe calls the page name, in this example “slider.htm” :
<iframe title="slider" src="slider.htm" width="100%" height="100%" scrolling=no frameborder=0 style="overflow:hidden" ></iframe>
