Placing 3 images across the top of a post

I am using the Twenty Twelve theme and I would like to place 3 thumbnail (150×150) images across the top of a post. Then I would like to place a paragraph of text below all 3 images. In a perfect world, the images would be evenly spaced across the top (left-aligned, centered and right-aligned) but right now I’d be happy just keeping all 3 images on their own line.

I tried placing all 3 left-aligned images in a DIV tag but the text still wrapped around the right side.

What is the “best practice” way to do something like this?

What is the easiest way?

Is there a way to do it using only the Visual Editor?
