Don't use width="%15"
on your image. Instead, resize the image to the size you want it and use the smaller image (in your case it would be 112 x 25). The wrapping <div class="navbar-header">
is making room for a 744px wide image, but then on your <img>
tag you are scaling it down to 15% of it's original size.

Plus, its just a bad idea because the site still has to request and download the large file then resize it. It would make your site faster if you just make a smaller image yourself and reference that one with the smaller size.
