If I load an image using this html on my sidebar
<img src="http://fc06.deviantart.net/fs70/f/2012/099/d/f/stackoverflow_16x16_icon_by_muntoo_stock-d4vl2v4.png" height="200px" width="200px" alt="image" />Would it load any faster/slower than if I instead put on the sidebar where my style.css (which is called in the header) has
.image {
width: 200px;
height: 200px;
background-image: url('http://fc06.deviantart.net/fs70/f/2012/099/d/f/stackoverflow_16x16_icon_by_muntoo_stock-d4vl2v4.png');
}<div class="image"></div>
