Featured Image Size on Posts

We are moving from an old theme that only required featured images to be 220x220 squares, where they were displayed within the top of the article aligned right.

With the Gavick News theme, these 220x220 image are appearing above the content, centered on the page. This results in a lot of white space on both sides of the square image.

Is there a setting or code manipulation that can be done to either
(a) display the image aligned right if the featured image is under a certain size?
or
(b) crop that square image to some sort of 3:2 aspect ratio, and then stretch it across the top of the story (even though it would degrade quality)

Could you please provide me with a URL to your new website with our theme activated, either here or via PM (click the “Private Message” text underneath my avatar) so that I may analyze it? It is a lot easier for us to diagnose issues when we have a live site to examine.
