Django Content Type Of An Image File

I want to check a file type before uploading it by: content = self.cleaned_data['picture'] content_type = content.content_type.split('/')[0] When I upload the picture I get an err

Solution 1:

imghdr.what will return image format as string (gif, png etc.) if the image is valid, or None otherwise.

Usage:

import imghdr
imghdr.what(value)

In the above example value can be either a file(-like) object or a filename.
