Two questions with one aim : to re-use an existing (XHTML) page design without having to create new layouts/images etc

1) Does anyone know how to ensure that all images on a page are resized to fit the browser page?

I'm hoping there is some phone setting or custom Nokia tag that makes images do this ??

2) If resizing doesn't occur is there any setting to remove the horizontal scroll bar even if an image exceeds screen width?

I would be happy to have the image clipped a little if it removed the horizontal scroll bar
