At the moment we have the JPGs (16 GB) only on hard
disk.
16 GB total or 16 GB each image? I assume total, as we're talking of
postcards. I don't know about your bandwidth but that should be quick to
upload. You can for instance use scp or SFTP to upload them to Tool Labs
https://wikitech.wikimedia.org/wiki/Help:Tool_Labs and it will be easy
for anyone, including Wikimedia Germany, to pick them up.
