Vertical Spacing Around Images

Good evening.

Fantastic theme – just beautiful.

I am looking for a global CSS customization so that the spacing above and below an image in a post will be reduced. Here’s an example of a post with vertical spacing that I’d like to reduce: http://freewhitewater.com/how-rural-wisconsin-campuses-coerce-students-into-becoming-drug-informants/

(The photo is of a young man holding a playing card.) Is there a way to reduce the space between the caption and the photo, and then the caption and the following paragraph?

Best,

Adams
