Part of the idea of having defines is that it makes it easy to adapt code....so for each extra chip you just need to change the default address to the address set on the chip and change the datasets and it should work out of the box.
(not that I know what you intend to do! 
)
If you read the notes in the example code (AND the datasheet)...the picture register setting is overidden by the movie reg. setting so unless you are using pictures it doesn't need to be there...
...however it IS there to show how it can be used.
