3 cols (css holy grail) w images?

There’s no shortage of examples of doing 3 cols (css holy grail). However, it seems that EVERYONE I’ve found contain text, not images in the left and right cols.

Can anyone point to an example of a 3 column css layout in which the left and right column have images in them? And by that I mean images beyond the size of just a small 60x60 (or so) thumb.

In particular I’m trying to find an example of putting a 60x160 image in the left column and 300x250 in the right column (these are 2 of the IAB banner size guidlines). I’ve tried myself, and I keep going off the page. Anyone tried this or know of an existing example? TIA.
