I’m working on a client project right now that makes heavy use of embedded videos. It’s exciting because as someone who primarily develops themes and plugins for marketing sites (and whose personal blog is almost exclusively text and code) it’s rare that I really spend much time with the rich-media embeds that have been getting so much attention from the core team over the last few releases.
As I started playing with the video embeds I immediately noticed an issue – there was nothing in the media widget that allowed authors to set a poster frame (the static image that appears in the video player before the user clicks the play button). I checked the documentation for the
shortcode and found that the shortcode does accept an optional poster attribute, which allows authors to specify a poster image.
