Wrap a caption next to an image like this

How would I go about setting up my CSS and my images to allow for a great effect such as the one shown here.

The caption autosizes it seems to the size of the photo. I have tried to pick apart his code but I cannot for the life of me figure it out.

Here is the style.css – http://www.firstshowing.net/wp-content/themes/fsnetv2/style.css

Any help would be awesome. I want this effect, not the plugins out there that auto add a caption underneath.

Thanks
