[BUG] invalid OG image tag when no image is present about seo

[GwendolenLynch]

Quoth http://ogp.me

The four required properties for every page are:

• og:title - The title of your object as it should appear within the graph, e.g., "The Rock".
• og:type - The type of your object, e.g., "video.movie". Depending on the type you specify, other properties may also be required.
• og:image - An image URL which should represent your object within the graph.
• og:url - The canonical URL of your object that will be used as its permanent ID in the graph, e.g., "http://www.imdb.com/title/tt0117500/".

@GawainLynch Exactly. I already created another issue (#67 ) with a feature request to include a default, at @bobdenotter 's request. :)

Yeah, saw that one come through after … Not sure how we missed it here, I've had that in my OG extension since day 1 (early 2.0-dev)

Well, in 99% of the pages there is an image present. I just built a site that had a contenttype without any media. :)
