Featured Image Setting Change

I installed the south theme on my client site but I find that the default featured image width was set too small. Right now the featured image width setting is width="663" which makes text with short words wrap oddly around the image. See this page for example:

I wonder if I can change the featured image width so that the image appears wider than now and the text around it could wrap properly.

Hi!

As you can see the featured image width you have chosen is almost the same as the width of your content. There is no place for any word on the right side of the image except for "I" . If you choose this width for this image you would better center align it on page Theme Settings --> Layout in the dashboard of the theme.

Thank you Dave, that was very helpful!
