Image viewer that can view multiple images at once

[HanneMaes]

I'm looking for an image viewer that can view multiple images at once, like in this video.
Any sugesstions?

Open a picture > click menu button > click Show > enable Pictures gallery

The problem is that don't allow opening more pictures in the same window, it only shows more as preview under the actual one already opened.
