How can I stack images vertically in a div

Question

I want a div containing three images and I'd like the images stacked vertically.
I've set the div width to the width of my images and that doesn nothing. Here's my code:

.detailImgWrapper
    {
    display: inline;
    position: relative;
    width: 25px;
    top:-210px;
    }

.detailImgWrapper img
    {
    visibility: hidden;
    padding: 0;
    padding-top: 10px;
    display: inline;
    width: 25px;
    height: 25px;
    }

Thanks for taking a look.

set your images to display: block, and they should stack vertically.
