Some images inside a table are not "wrapping", and accumulate themselves horizontally in FF only. This is not happening in IE or Chrome.

this is the url: www.aica.org/front.php
The images that are not wrapping are the ones that are in the rightest column, as you can see.

There are some banners that should wrap (the longest ones, that are >120px) and others that should not (the ones that are <120px).

As you can see, in IE or Chrome they are doing that naturally.
