View | Customize This Folder | Select Pictures or Photo Album
You can view your pictures as a filmstrip in any My Pictures subfolder or
any folder customized as a pictures folder.
Filmstrip view is available in picture folders. Your pictures appear in a
single row of thumbnail images. You can scroll through your pictures using
the left and right arrow buttons. If you click a picture, it is displayed as
a larger image above the other pictures. To edit, print, or save the image
to another folder, double-click the picture.
-----
This issue can occur because the Filmstrip feature requires that Show common
tasks in folders be selected to view the full functionality.

the My Computer icon.
