resolution

I've read all over the Internet that I should not define fonts (or anything) with absolute pixel height/width/size and instead, use EM ... so that on higher resolution displays, my web site can scale appropriately.

However, what do I use to define IMAGE height/width ... because images won't scale well (they look pixelated)

UPDATE:

To clarify, I'm not referring to page zoom. I'm referring to how to make my web application resolution independent so that it will look correct on higher DPI displays.
