GetFeaturedImage
|
|
|
|
This partial gets the featured image for a given page.
|
|
|
|
If a featured_image was set in the page's front matter, then that will be used.
|
|
|
|
If not set, this will search page resources to find an image that contains the word
|
|
"cover", and if found, returns the path to that resource.
|
|
|
|
If no featured_image was set, and there's no "cover" image in page resources, then
|
|
this partial returns false.
|
|
|
|
@return RelPermalink to featured image, or an empty string if not found.
