Carte Noire is designed to start each article with an all-white image as a
thumbnail. These are created by adding a
thumbnail parameter to the article’s
YAML frontmatter. This thumbnail parameter is processed in one of two ways,
images specified in
_data/thumbnails.yml or using Font Awesome.
To use your own custom images as a thumbnail you must upload them to a web available
location (I use Imgur) and then you need to add the url to
with an associated keyword.
You then add a
thumbnail option to the article’s frontmatter and provide the keyword
for that thumbnail.
This allows you to re-use thumbnails across multiple articles without having to specify the url each time.
If jekyll can’t find a corresponding image in your
thumbnail.yml file then it
will assume you want to use a Font Awesome icon instead. You can find the full
list of Font Awesome icons here.
So for example if your article is about android and you want to use the android icon from font awesome you can just specify the following in your frontmatter.
Then in the future if you decide you want to use your own android icon you can just
add it to
_data/thumbnails.yml which will override it for all articles using
the android thumbnail.
