[Mediawiki-l] mass upload

[Stuart, Ryan (CIV)]

Hello all,
 
Is there a way to upload files en masse to wikipedia.org? My
organization has been running its own MediaWiki installation but would
like to move these files to Wikipedia. We have 771 pages and 156 image
files in our current wiki.
 
We'd like to start our own portal on the subject (net-centric warfare)
as none currently exists. 
 
All advice appreciated, including whether there's a better way than a
portal.
 
Thanks
Ryan
