You can do this:

1) Edit templates/tmpl_uni/_footer.html

<div class="bottomBlock">
<div class="clear_both"></div>
<!-- __dol_orca_ray__ -->

<div class="bottomImages">
<img src="/xmyfiles/footerlogo.jpg" width="740" height="75"/>
</div>

<div class="bottomTexts">

2) Edit templates/tmpl_uni/css/general.css

Find this block and change height from 60 to 150 like I see more have do bellow.

.bottomBlock
{
position:relative;
//height: 60px;
height:150px;
border:1px solid #D0D0D0;
}

That's it!
