Have you thought of using ImageMagic Terry? I use it to convert all the
pictures of my digital camera into more appropriate sizes. As they all
have the same starting size I do % reduction so that the aspect ratio
stays the same.

Here are the two appropriate lines from my script

convert -geometry 50%x50% -border 3x3 -bordercolor black $original  $resized
convert -geometry 6.5%6.5% $original $thumb

This creates one image half the size with a black border around it and
also a small thumbnail.

Too see an example of the output goto

there are both landscape and portrait orientations. Clicking on the
tumbnail shows you the larger image.

I have found ImageMagic very powerful and the PerlMagic interface to it is
great as well. You could use that to get the size of the origianl image
and do all of the maths. Also scripting the whole thing makes it easy,
save all that clicking and you can do a batch at a time.
