So 1.6 is not going to have the ability to upload using the xp_publish anymore? If so, how can that be done? What is the best alternative to upload multiple images and have them added in the order of name ascending?
To upload images use either one of the available upload methods (HTML5 recommended) or upload your files via FTP and then use the batch-add feature. To display them by name ascending, just set this in the config: https://documentation.coppermine-gallery.net/en/configuration.htm#admin_thumbnail_default_sortorder
