One of the better features added to Google Sites in 2019 is the image carousel option. With image carousels you can display a large collection of images in a gallery that visitors can browse through. As you can see in the video included below, your image carousel can take as many or as few pages as you want.

Applications for education
Image carousels are great for displaying a series of photos from a school event such as a holiday concert or an excursion. Image carousels can also be great for students to share photos on their own sites to document the process of building something for a classroom project. The student can place a caption in the images to help explain the importance of each image. Google Sites contains an option to easily place the images in the carousel. That caption option is shown in the video above.
