In order to share an interesting page, it’s enough to right-click on any place of the page and select „Share on Google+“. You can post the picture you liked in the same way. In order to do this, right-click on it. If you share a page on YouTube, then the video will appear in the feed of your posts. The most important thing is that you do not need to go to your page of G+. Keep a blog without tearing yourself from the view.
