-Note that the thumbnail summary can be quite big. Use viewer like {{deb|feh}} to view it. The same application can be used to view thumbnails easily:
-<source lang="bash">
-THUMBDIR=thumbnails
-THUMBSUMMARY=summary.png
-view_thumbnails()
-{
-	# sudo apt intall feh
-	feh -dF --zoom fill $THUMBDIR
-}
-view_thumbnails_summary()
-{
-	# sudo apt intall feh
-	feh $THUMBDIR/$THUMBSUMMARY
-}
