One of Typical’s neatest enhancements is the provision for HTML5 post thumbnail 1 (‘featured image’) display. If you add a featured image to your post, the theme will insert this image — along with its caption — at the top of your post using the
<figcaption> elements. Post thumbnails are not mandatory: The
typical_post_thumb_figure() function does not run unless one is provided.
Post thumbnails, like avatars, in Typical are displayed at 2x pixel density for high resolution screens. This is achieved by creating a new thumbnail size using
add_image_size( 'Typical Thumbnail', 600, 600, true ); and displaying it at 300px x 300px. Uploaded images that do not have square dimensions will be cropped.
