Upload gallery by ftp
Have you tried himuesgallery module?


  It implements a new node-type to show all pictures in an specified directory. Descriptions will be automatically generated from the filenames, so there is no need to administer a seperate databse table, etc.
  My gallery works with automated generetated thumbnails so it seems to be fast.
  It can use Lightbox2 or colorbox to simply generate lightshows and naturally it makes use of user configurable css-files to style the gallery. Some styles will be delivered with the module, so users don't be worried about this.
