In plain English: A slideshow is a presentation that shows a series of pictures one after another on a screen.
"The teacher projected a slideshow on the screen to explain the history of the city."
Usage: A slideshow refers to the digital version of an old-fashioned slide show where images are displayed sequentially on a screen rather than projected from physical film strips. Use this term for any automated sequence of photos presented in software like PowerPoint or Keynote, distinguishing it from manually flipping through individual pictures during a speech.
The word slideshow is a straightforward combination of the words slide and show that describes a presentation using sequential images. It entered English as a compound term to describe this specific type of visual display without any shift from an original meaning.
