Is it possible to use my own shortcode with this syntax…
`![San Francisco from the Treasure Island](https://img.mcdowell.si/2013/06/wpid-20130623_104914_20130623220546093-1.jpg "San Francisco from the Treasure Island")`
rather than this:
`{{< img src="https://img.mcdowell.si/2013/06/wpid-20130623_104914_20130623220546093-1.jpg" title="San Francisco from the Treasure Island" >}}`
I would like to override the default Hugo img rendering without having to replace the content in all markdown files. The custom shortcode created a figcaption which Hugo does not seem to support.
