Photo Finale allows you to customize how you view thumbnails (the miniature pictures at the bottom).  The section of the main screen just to the right of the thumbnail box is where the settings are for the thumbnails.  This is what the controls look like:

 

 

      The slider bar that looks like a volume control allows you to make the thumbnails larger or smaller. 

      The Detail Displayed drop down box allows you to select the amount of detail you want displayed with each thumbnail.

      You can choose to display the photo only by selecting None.

      You can choose to display Some detail which will show the photo name and date taken below the thumbnail.

      You can choose to display More detail which will show the name of the photo, the date the photo was taken, the dimensions of the photo, and the megapixel count below the thumbnail.

      You can choose the Table view which will not show the thumbnail.  Instead, it will display the name of the photo, the date it was taken, the dimensions of the photo, the megapixel count, the focal length, the exposure time, the camera model, and the camera manufacturer in a table format.
