 * i think it might be security settings on the gallery directory.
 * i’m on a windows server.
 * when uploading images i get errors, but the pictures are uploaded.
 * on the last batch i uploaded, thumbnails were not generated and i got error “
   1” when trying to batch generate them.
 * what should the gallery security settings be on the gallery directory ?
