If you insist in using reference implementation only, then you can't go around using a nested h:dataTable and/or h:panelGroup and a good shot of CSS to get it aligned nicely. You can then use JavaScript the smart way to show/hide row details.

Here's a basic kickoff example:

The toggleDetails() function can look like (note that it takes JSF generated client ID into account):

function toggleDetails(image) {
    var detailsId = image.id.substring(0, image.id.lastIndexOf(':')) + ':details';
    var details = document.getElementById(detailsId);
    if (details.style.display == 'none') {
        details.style.display = 'block';
        image.src = 'collapse.gif';
    } else {
        details.style.display = 'none';
        image.src = 'expand.gif';
    }
}
