Do you mean the photos that came with the iPad that you use when selecting a new wallpaper? If yes, then there is no way for you to access those photos on a stock iPad. They are in a different file and Apple has not elected to make them accessible for copying or sharing.
If you have a jail broken iPad, you can access those photos. But, not on a stock one. Sorry.

P.S. And, since this question of yours has nothing to do with taking any type of poll, I'm moving it over to the Help section. Thanks for your understanding.
