A very easy way of creating rotating banners is by adding the following line in your "phpinclude_start" template (replace X with the number of banners you are rotating)
Code:
$bannerrand = rand(1, X);
and then use the number generated in your template whereever you want the banner, for instance in the "header" template. Example; rotating three banners (X=3 in the code above):
Code:
<if condition="$bannerrand == '1'">
<a href="Banner 1 hyperlink"><img src="Banner 1 Image URL" /></a>
<else />
<if condition="$bannerrand == '2'">
<a href="Banner 2 hyperlink"><img src="Banner 2 Image URL" /></a>
<else />
<a href="Banner 3 hyperlink"><img src="Banner 3 Image URL" /></a>
</if>
