Should load images with relative paths from the markdown file's location

[edbrannin]

Images in my markdown file aren't loading, and it's not clear to me where it's trying to load them from.

Input markdown:

If the lines are not randomized at all, the chart will look like this:

![input line number = output line number](lines-chart-not-random.png "input line number = output line number")

If the lines are randomized, the chart should look more like this:

![these lines are in random order.](lines-chart-random.png "these lines are in random order.")

Compiled HTML:

<p>If the lines are not randomized at all, the chart will look like this:</p>

<p><img src="lines-chart-not-random.png" alt="input line number = output line number" title="input line number = output line number" /></p>

<p>If the lines are randomized, the chart should look more like this:</p>

<p><img src="lines-chart-random.png" alt="these lines are in random order." title="these lines are in random order." /></p>

Visible result:

I have triple-checked that the images do exist in the same folder as the README.mdown this is from.
