Modify Picassa template

i have a picasa template(flash page flip gallery), that i downloaded from this link: paulvanroekel (dot) nl (slash) picasa. it can show images in a flash book fashion. but, the problem, i have with it, is that is show only left to right. i need it to be modified that it should work for right to left. (as may have seen any arabic book) first page of the book is the most right, and last is the most left. or if anyone can create any similar template that i am able to use it for right to left orientation.
