Flash mouse over question

Whew, Forgive me im strickingly new at flash, And im merely 16 years of age
any how, Im creating a site and as navigation i am using images of keys, I would like for an image to display when the mouse rolls over the keys. For example, say key 1 is biography, when the mouse rolls over the key i wan’t an image I made in photoshop with “biography” on it to be displayed directly below it, how would I go about doing this?
(just for a visual)

Also when the keys are clicked i’d like the content to be displayed in a designated are with a scrollbar, i suppose in an iframe?
