Facebook has recently launched a new photo viewer in which pictures appear in a black background pop-up window. More and more people have started to hate it as it doesn’t allow to save/download photos by right clicking and then “save image as..”. (To be honest, pictures are far better to look at with white background) 😀
To switch back to Facebook’s Non-Pop-Out Photo Viewer….Just hit refresh in your browser—Ctrl+R, Command-R, or F5 in most cases. Check the video below see what exactly you have to do.
Another way to open pictures in old photo viewer is to remove the “&theater” string at the end of the URL.
