By monetize you mean make $100 or so a month right ?

With RPM's around a few dollars for AdSense isn't that the most he would be looking at in revenue, or am I missing something ?

Pretty much. Buddy of mine runs one of the most popular wallpaper sites and the ads make pennies on the dollar. You can't really monetize a wallpaper site at all (especially if you aren't the one making the wallpapers).
