slideshow

Slideshow is a modern concatenation of "Slide Show". A slideshow is a display of a series of chosen images, which is done for artistic or instructional purposes. Slideshows are conducted by a presenter using an apparatus, such as a carousel slide projector, an overhead projector  or in more recent years, a computer running presentation software. The term originates from the use of slides which have been around for many years. Slides originally were projected on movie theater screens by magic lanterns as part of the program of early moving picture shows.
