gatsby-browser.js: not changed gatsby-ssr.js: not changed

Before submitting this issue I tried:

• changing the image format from PNG to JPEG
• using different images
• changing the path of the blog post
• resizing the image
• upgrading to latest version of plugin

Steps to reproduce

Here’s a page on my blog with the issue: https://patrickcanfield.com/blog/2016/01/15/sleep-mindfulness-art/

Here’s the source code for that post: https://raw.githubusercontent.com/pzatrick/patrickcanfield.com/master/gatsby/src/blog/test.md

For now my workaround is to use an img tag with an absolute URL to the image in the Gatby-generated static assets.
