ie7 css html padding issues

hi i've encountered a really annoying problem i'm about to create a imagegallery as can be seen here http://freeri.freehostia.com/test/

the issue here is that in all later browsers they take in count that the element before the pagination buttons has padding therefor the page buttons get placed accuratly 70px beneath last row of images while ie7 does not so it get's placed only after what margin i've given the buttons that is 10px beneath

screenshots can be seen here http://browsershots.org/http:开发者_如何学编程//freeri.freehostia.com/test/

try this

.last{
float:none;
margin-bottom:70px;
margin-left:0;
}
