Steps:

• Visit Profile → Manage → Edit Profile Picture
• Upload a Picture
• Turn back to Profile → Manage
• Visit the filename of that new Picture (but also any old picture) (pictures are mentioned from the right sidebar)

What happens:

• File is not editable: «No one can take this action»
• File cannot be deleted: «No one can take this action»
• (File can only be detached)

What should happen instead:

• File should be Editable by the Author (to update its quality for example)
• File should be Deletable by the Author (to fix a huge mistake for example)
