2. want make art slide on piece of art in header when browser resized. involve layering of art too.

well, if knew how it, show you...lol. ok...i try again.

1. not want create new piece of art every time client decides change background of header. so, main logo png or gif clear background in it. then, want able switch out images underneath logo art without doing changing image under logo itself. bottle of water mountain spring week one, then, mountain vista week two, , forth. but, logo not change. sits on top.
2. not sure how word better....i'll work on this.

this why having trouble searching information. don't know keywords use.

i hope clearer.....
