If you look at the HTML, you’ll notice the widget code is setup to show the image, then the title, and then the text….so it will only display in that order. That’s just the way it’s designed in Genesis. In order to show the title on top, it would have to be first, before the image…..especially if you want the image to float to the left. So you wouldn’t really be able to have the title on top of the image since the image shows up first in the code.
The only thing I can think of to change the order is to use a plugin called “Genesis Feature Widget Amplified” – http://wordpress.org/plugins/genesis-featured-widget-amplified/ …..but I’m not sure if it will work with the latest version of Genesis 2.0
