Changing banner with tabs and text - suggestions wanted

i’m finding it hard to find what i would like for my site. If you take a look at it has a nice banner system that allows you to click on a tab and bring back more info.

I’ve seen ones that change the banner and cycle through but they don’t have all of the information showing for each tab, normally just a number.

I have no idea what this is called to be able to find similar systems. Anyone know of any? or know what the term for this is to be able to search.

i really only need one with 4 tabs that are relatively static. This is my site where i’m using one i’ve put together but its a big of a bodge and i need a more reliable one.

alternatively i was thinking maybe a flash version loading external pics and text? what do you think

many thanks
