Media can be added to your blog in one of two ways: uploading to your blog's Media Library or embedding media from an external source.
Uploading media to your blog
It is recommended that you only upload small files such as photos, PDFs and audio files to your blog. Large files such as videos should be embedded in your posts from an external source such as YouTube or Vimeo.
Embedding media on your blog
Media can be embedded on your blog by simply embedding a URL into a blog post.
