Well guys the pics are finally deleted, a friend of mine came over and showed me how.
Pics taken with the iPad can simply be deleted by clicking the delete button on the iPad screen. However, pics transferred from another source, ie. my laptop, to the iPad can not be deleted by clicking the delete button, the button doesn't work. I had to delete all my files transferred to the iPad through iTunes, then I transferred only those pics from my laptop to the iPad through iTunes. I find this absolutely stupid, it's called iTunes so I'm expecting music, not pics, it should be called iMedia so it encompasses all media, pics, music and video.
I love the quality of Apple products, second to none, love the look and many of the applications. But this is so friggin' stupid that you have to go through hoops, as Pecker said, just to simply delete a pic, how arrogant of them.
Thanks for all your posts guys.
