Hoe kan ik de beelden wijzigen in de index.tpl

Hallo, dit volgend stukje is de afbeelding op de hoofdpagina van http://print.dvcgraphics.com

<div class="big-img-foot rc3 clearfix">
		<div class="c-banners g-marg  g-border  g-graund_6 g-shadow">
				<h2>{translate('TEXT_FIRST_FRONTLINE')}<span class="g-blue_bg g-graund_6"></span> </h2>
				<p>{translate('TEXT_SECOND_FRONTLINE')}</p>
			<span class="b-banners_butt"> <a href="{$href.tshirtbuilder}"></a> </span>
		</div>
	</div>

Ik zou graag dit beeldje laten switchen door enkele andere beelden.
Ook de tekst zou dan moeten veranderen. Zou dit moeilijk zijn?
Ik zie nergens geen link naar de afbeelding, dus zal het iets met classes zijn of zo. (denk ik)
Beelden mogen ook gewoon naar beneden vallen en een ander in de plaats. (is gelijk voor mij)
Ik wil gewoon dat mensen zien dat er meer te beleven valt dan enkel textieldruk.
De site zal dan ook wat dynamischer lijken (zijn)
De volledige code van de .tpl file is het volgende:

{strip}
