Gotten old and rusty! Help with this please

Hi All,

Been away from flash for a while and have got very (very) rusty. Have a look at this:

www.howie* (sorry 'bout the stars, just remove them!)

Look at the two photos at the bottom (Features). See how they bring up a bar of info on hover. Probably quite simple and I hope I’m not wasting anyone’s time here but can anyone give me a pointer to try to do this sort of thing?
