I wonder why you are analyzing the code !!

Bv will create the rollover for you, with the images you tell it to use, and will create the code correctly, IF you link the rollover to a whatever page!
Why are getting confused with code to copy / paste or modify???

Just use the BV built in tool for rollovers!

If you wish, use my contact form to send me your BV pages for index and about us, and i will fix them for you.
