Unfortunatly, I dont find yet a way to upload multiple files using wordpress, but I made a new plugin page to sync the folder and database (so, now you be able to upload files and sync database with a click).
If anyone want to test, send an email (I'll send the changed version to official developer too)
* Upload to folder, and sync by admin panel
* Edit album definition (title/description)
* Edit image definition (change album/description)
* Fix some bugs with exclusion of same image with another id
* Renamed the tables adding the 'mg' prefix to avoid conflict with another plugins
