Gallerad.pl do this?

Will galleryad.pl, via cron or something as simple, automate the upload from local server command in Gallery 2?

Also, does Gallery delete from the upload directory when it imports or leave the files there? Does Gallery skip files with the same names that already exist in its database?

And last, is there any way to get Gallery to skip uploading from local server files that meet certain criteria; for example with "thumb" in the name?
