When you are working in Thumbnail or Filmstrip view, file names display under each picture by default. You can hide the file names to fit more files in the view.
On the View menu, click Show File Names.
If the option is cleared, Microsoft Picture Manager won't display the file names. If the option is selected, Picture Manager displays the file names.
If you hide file names, you can see them under the preview pane when a picture is selected.
