Apps How to make images bigger?

[Deco354]

I've created a separate layout for large screened phones. I need my ImageButtons to do one of two things.

*Stretch the images within them when I make the imageButton bigger.
or
*Replace the images with larger versions based on the phones screen size (Note I say size not density)

An image of my app in it's current state with an enlarged imageButton highlighted.
Thanks
