Move a gallery to another existing Gallery-Server

Hello!

Perhaps you read about closing www.mygallery.cc
... on mygallery.cc I created a nice gallery with all winners of a forum-contest.
Old URL: http://mygallery.cc/hall-of-fame/ (will shutdown soon)

Now we have to move this gallery to another (existing) gallery-server.
Of course, I have no access to the filesystem of the mygallery.cc-server. But, of couse, I have full permissions on my gallery-folder @ mygallery.cc

At first, I thought, I could login at the new gallery, choose
[add photos]
[Or, upload any images found at this location. The location can either be a URL or a directory on the server. ]

But when I submit the URL
http://mygallery.cc/hall-of-fame/gewinner_2003
, gallery only offers to tranfer the *.thumb.jpg files

Is there any posibility to transfer an whole gallery?
Best with description, but I would be happy even if I could transfer only the full-size-jpgs.

Thanks,
Jan

Gallery URL (optional but very useful): http://mygallery.cc/hall-of-fame/
Gallery version: source Gallery v1.4.1

Thanks for your help, Jan. However, I moved my URL to the new server which makes access to the old server impossible. There was no way to maintain the same URL on two different servers. I suspect this means that I'm doomed to manually recreating everything from scratch. I do, however, have a backup copy on my computer. Could that be of any value?

Thanks very much,
John
