Twitter Bootstrap v2.3.2 alignment blocks height (vertical align middle and height 100%)

Question

I'm trying to align the text blocks on the height of the surrounding images. (something like this http://s14.postimg.org/gqxt3rmu9/image.jpg)

This method vertical-align: middle with Bootstrap 2 did not work. I would be grateful for any help.

<div class="row-fluid">
<div class="span6">
    <div class="row-fluid">
        <div class="span3">
            <img src="img/gallery/1.jpg">
        </div>
        <div class="span6">
            Text
        </div>
        <div class="span3">
            <img src="img/gallery/1.jpg">
        </div>
    </div>
</div>
<div class="span6">
    <div class="row-fluid">
        <div class="span3">
            <img src="img/gallery/1.jpg">
        </div>
        <div class="span6">
            Text
        </div>
        <div class="span3">
            <img src="img/gallery/1.jpg">
        </div>
    </div>
</div>

style

.row-fluid > .span3, .row-fluid > .span6 {
  display: inline-block !important;
  vertical-align: middle !important; }
