Hello,
 
we have access to 30000 images of historical postcards (from 1897 to 1989) of one publisher in Saxony, Germany. Our small team of Wikipedians has the permission to upload this images to Wikipedia Commons. In the last months we add metadata and categories to 53% of the images in a MySQL-Database. Maybe in two or three months we are finish this job and ready for upload. 
 
Now we search for a tool for the batch upload and found the GLAMwiki Toolset. Maybe this is our solution, but if I understand the user manual, then we need the images online with a URL. At the moment we have the JPGs (16 GB) only on hard disk. And also nobody has so much webspace.
 
It is possible to upload this direct from hard drive with a GLAMwiki Toolset?  If this not possible, can I bring the hard drive to Wikimedia Germany?  Who is the contact in Berlin?
 
Or any other possibilities?
 
Best regards
Stefan Kühn
