Elmore,
see this article about powerpoint posters first
Print posters or other large format output
http://www.pptfaq.com/FAQ00537.htm
Then if it was me, I'd create a blank slide in powerpoint (in the same
proportion as your poster), then open your other slides, then view the
"slide sorter", then copy and paste each slide on to your new blank slide,
resizing them as you go along,
cheers
