A quick example of how to start using Thumbnails in your articles.
If your average directory for an article looks like this:
content
└── awesome_article.md
You need to change it from a single markdown file into a folder. Create a directory with the same name of the article, inside create a index.md file. You’ll get a structure similar to what’s below.
content
└── awesome_article
└── featured.png
Inside the article you can now add an image file (almost all formats are supported but we recommend .png or .jpg) that starts with feature*. Example below.
content
└── awesome_article
├── index.md
└── featured.png
This will tell Blowfish that this article has a feature image that can be used both as a thumbnail across your website as well as for oEmbed cards across social platforms. As an example, you can try copy pasting the URL of this article into a platform that shows oEmbeds (e.g. Twitter, WhatsApp, Telegram, etc) and see what is displayed.
