Captions Under Thumbnails

Trying to figure out a way to display thumbnails horizontally with captions without using tables. Ran into this suggestion to use a DL tag (data list) which has a DT tag for a title (which can be the image) and a DD tag for data (which can be the caption.)

<style type="text/css">

#wrap {width: 500px;
}
dl.gallery {float: left; width: 150px; padding: 2; border: 1px #f00 solid; margin: 0;
}
dl.gallery dd {padding: .0em; margin: 0;
}

</style>

Not sure this is easier than tables which I'm using here:
