- Lots of bug fixes: photos and users can now be saved
- When creating a new fichier: when the fichier fails to be created then also delete its parent photo. This is because a new fichier is made only for new photos. And if the fichier was failed to be created and it is because the file of the fichier failed to be created then we do not want the photo. In other words, we do not want photos that were not properly saved to the hard drive.
