It appears that tiltviewer always leaves a space on the top and bottom
This is likely to be caused by the CSS on your web page rather than by TiltViewer itself.
I may be wrong, but the aspect ratio of the #flashcontent div appears to be always square.
TiltViewer can be embedded into a #flashcontent <div> of any aspect ratio you like.
Try the following. Take the sample gallery from the TiltViewer download package as a starting point. Open the 'index.html' page in a plain text editor.
Change:
#flashcontent {
height: 100%;
}
.. to:
#flashcontent {
height: 400px;
width: 800px;
}
... and change the body's background's color from black (#000000) to white (#ffffff) so that you can see the edges of the gallery.
Open 'index.html' in a browser to view the gallery and you will see that the gallery's aspect ratio is rectangular (rather than square) and that the gallery itself goes all the way to the edges of the Flash stage (as can be seen when clicking on an image to enlarge it).
Try setting your #flashcontent <div>'s dimensions in absolute pixel values (rather than as percentages) and temporarily change the color of each <div> in your own page to see where the extra space is coming from.
