Information Window
Tapping on the Information Window function opens a screen that
covers the bottom half of the thumbnail's viewing area. The file size
and image type are presented in this screen for the selected image.
Use the navigation bar on the right side of the screen to scroll down
and select each image. Tapping on the thumbnail selects the image. A
thin white border will surround the selected image.
To remove the Information Window, tap on the View option. The
Information Window function has a checkmark beside it, tap on it to
deselect the Information Window.
