Pre-filtering files before upload (Cannot exclude existing thumbnails, and program ignores mode 000 files)

[derekatkins]

Hi, I am trying to load a bunch of existing images into piwigo using this program. They are currently in folders on the webserver with thumbnails for my existing (manual) photo gallery. I want to only import the main images and not the thumb images, however:

1. There appears to be no way to filter out the files by name
2. Even when I set the thumbnail files to mode 000, the sync program can still read them

It would be a nice feature to be able to pre-filter files.
