Subject: [PATCH] layouts/_default/single.html: Only get imageConfig on local
 images
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Don't try to get image information when the image isn't local. We
generally expect that images are in the local filesystem's static
directory, but if the user has specified a remote image—ie, with
an http:// or https:// prefix—then we shouldn't try imageConfig.
