Blogger added a feature that makes it easier to view multiple photos. When you click on an image from a Blogger post, a LightBox-like overlay shows a bigger version of the image and lets you view the other images in a slideshow. The feature was borrowed from Google+, it’s enabled by default and can’t be disabled from the settings page.
If you want to open an image in a new tab, middle-click on the URL displayed below the image or right-click the link and select “open link in new tab”. The slideshow supports keyboard shortcuts: left/right arrows, j/k, n/p to navigate, Esc to close the slideshow.
