Where can you find the thumbnails of each slide in a PowerPoint presentation?

In a PowerPoint presentation, the thumbnails of each slide are located on the left side of the window in the Slide Navigation Pane. This pane allows users to easily view and select different slides within their presentation. The thumbnail images provide a visual representation of each slide, making it simple to navigate through the slides, reorder them, or edit specific slides as needed. This layout supports efficient presentation management, particularly in presentations with many slides, allowing for quick access and organization.
