With the Flickr embed block, you can add photos and videos from Flickr to your posts and pages. However, when you click any photo or video, it will take you to Flickr where you can see photos and play videos.
You can also embed photo albums and galleries with the next/previous arrow links. You don’t need a Flickr account to embed photos or videos.
Note: With video, the page/post only displays the image of the video. There will be no play/pause button. By clicking on the video, it will be redirected to the corresponding Flickr page to play.
You can only share those photos and videos which are visible to everyone(public). Some publishers put restrictions by setting privacy.
