Problem z ładowaniem zdjęć za pomocą formularza

Czesc wszystkim.
Jest to moj pierwszy post. Zaczalem przygode z Django i napotkalem pierwszy problem w zwiazku z czym bardzo prosze o pomoc :)

Z poziomu administratora w Django jestem w stanie ladowac zdjęcia na serwer, jednak z formularza na stronie jest to niemożliwe.
Jedyne zdjęcie, które można przesłać za pomoca formularza, to domyślne zdjęcie, które ustawiłem w pliku models (default="user.jpg").
Jeśli usunę opcje domyślnego zdjęcia z models i zaladuje dowolne zdjęcie za pomoca formularza to wyskakuje ponizszy błąd:

Error during template rendering
The 'image' attribute has no file associated with it.
error at line 10
