Can't add a zip archive in existing gallery

[Vladimir Vasilenko]

Hello.

django-photologue 3.1.1.  I have the gallery with photos. If I add there any zip archive I get some messages:

• Did not create photo "%(filename)s" with slug "1" as a photo with that slug already exists.
• Did not create photo "%(filename)s" with slug "1" as a photo with that slug already exists.
• ......
  
• Did not create photo "%(filename)s" with slug "1" as a photo with that slug already exists.

What it is wrong?
