newbie database help

[CogyFarm]

I'm trying to create a database that has a form that is filled out from 
either a contained library of data or with new unknown data.  The 
hardest part is I want the user to be able to see a larger ( higher 
resolution ) image of the car if they do some action (hover?) over the 
image that the library has.  Also each car photo is preceded by the year 
then the identifier.  The problem comes in when there is more then one 
photo available.

2004-001a.jpg
2004-001b.jpg
I need them to be able to "cycle" through each photo till they see the 
one they want and then associate that particular photo with the data in 
that record.  I want this to be as automated as possible.  Can anyone 
point me in the right general direction?  I just dl'd revolution and 
Dreamcard last night.  I have no idea what I'm doing yet or even which 
version I need.
