Title: Fix for saving image in database

Because of following changes in ```file.py``` of previous commit :
- ```if img_type == "" or img_type == None:```

Image without tags was giving following error :
- ```Some Exception: .jpg Execption: 'NoneType' object has no attribute 'split'```

This is fixed now by :
- Changing ```tags = request.POST.get('tags')``` --to--> ```tags = request.POST.get('tags', "")```
