from awesome_avatar.fields import AvatarField

class Profile(Model):
    user = OneToOneField(User, related_name='profile')
    ...
    avatar = AvatarField(upload_to='avatars', width=100, height=100)

class AvatarChangeForm(ModelForm):
    class Meta:
        model = Profile
        fields = ['avatar']

def change_avatar(request):
    if request.method == 'POST':
        form = AvatarChangeForm(request.POST, request.FILES,
                                instance=request.user.profile)
        if form.is_valid():
            form.save()
            return HttpResponseRedirect('/profile/')
    else:
        form = AvatarChangeForm(instance=request.user.profile)

    return render(request, 'template.html', {'form': form})

Define some model for saving images:

class Images(Model):
    image = ImageField(upload_to='images')

Use form field for cropping image:

from awesome_avatar import forms as avatar_forms

class UploadAndCropImageForm(Form):
    image = avatar_forms.AvatarField()

def upload_and_crop_image(request):
    if request.method == 'POST':
        form = UploadAndCropImageForm(request.POST)

        if form.is_valid():
            Images(image=form.image).save()
            return HttpResponseRedirect('/any/')
