Making things "float" over the flash menu

When I change the logo module position's bottom margin to a negative number (to make the graphics in that position sit or float over the top of the flashy menu. However, when I do this, the graphic are hiding behind the menu. Even when I set the z-index to a ridiculous number, they stay put. It appears to be in front of the white border, but not the pictures.

Any ideas?

Here is the site: www.brorafting.com

You need to position it relatively to make z-index have effect:

.flashes_logo .custom IMG{
position: relative;
z-index: 10;
}

That did it. I had changed the position when I was trying a different format out and forgot to put it back in.

Thanks! Love your templates.
