Remove Page Navigation Numbers?

Hey my site is http://www.funksquare.com and on my posts I need to use the <!–nextpage–> code to go from picture to picture. I love that when I do this is shows a “next” and “previous” button, but when 10+ buttons are “1”, “2”, etc. It gets to be a bit much, is there anyway I can remove it without removing the next/previous buttons?
