A slideshow is a collection of pictures or images that are shown one after another on a screen, making it look like a mini movie. It's like flipping through the pages of a book, but instead of reading words, you get to see different pictures. The pictures can be of anything you want, like your family vacation, your favorite animals, or even just funny memes.
When you start a slideshow, the first picture appears on the screen and stays there for a little while before it disappears and the next picture appears. Usually, there are buttons or arrows to press if you want to go back to a picture you already saw or if you want to skip ahead to the next one. You can also set the slideshow to play automatically, so you don't have to keep pressing any buttons.
Slideshows can be really cool because you can add different effects to the pictures, like making them appear slowly or adding special transitions between them. You can also add music to go along with the pictures, like your favorite song or a tune that matches the theme of your slideshow.
Overall, a slideshow is a fun and creative way to display a collection of pictures for other people to enjoy.
