Here is a paragraph that precedes the image with a caption. The idea is that we want our pictures and their captions to be centered, but we don't want the lines of the caption centered, since that usually looks dumb, especially if only a word or two is on the second line of the caption. In this case, we decided to make the paragraph containing the caption 50% of the window.

Here is a paragraph that follows the image with a caption. It's just here to show what the block of text will look like. It doesn't have any useful information, so you should not waste your time reading it.
