Mapsoft ThumbNails, an Acrobat plug-in, is a powerful desktop publishing tool that embeds thumbnails within a PDF document.
A thumbnail is a miniature view of each page within a document.Thumbnails can be displayed in the Thumbnails tab located to the left of the document window (called Seiten in Acrobat 6).
You can also use the ThumbNails tool to remove any existing embedded thumbnails from within a file.
With ThumbNails you can export the images from your PDF into separate image files whatever the format (TIFF, JPEG, GIF, PNG).
