[Answer]-Create profiles simultaneously with registration

change photo field in userProfile like this:

class userProfile(models.Model):    
    name = models.CharField(max_length=30, default='')  
    user = models.OneToOneField(User)
    photo = models.ImageField(blank=True,upload_to=url)    
    email = models.EmailField(max_length=75)

def __unicode__(self):
    return self.user.username

This allow you to add userprofile without photo.

simply add userProfile when create new user like this:

def register_view(request):
    form = RegisterForm()
    if request.method == "POST":
        form = RegisterForm(request.POST)
        if form.is_valid():
            first_name = form.cleaned_data['first_name']            
            usuario = form.cleaned_data['username']
            email = form.cleaned_data['email']
            password_one = form.cleaned_data['password_one']
            password_two = form.cleaned_data['password_two']

            u = User.objects.create_user(first_name=first_name,username=usuario,email=email,password=password_one)
            u.save()

            #add user profile
            user_profile = userProfile(name=first_name,user=u,email=email)
            user_profile.save()

            return render_to_response('home/thanks_register.html',context_instance=RequestContext(request))
        else:
            ctx = {'form':form}
            return render_to_response('home/register.html',ctx,context_instance=RequestContext(request))
    ctx = {'form':form}
    return render_to_response('home/register.html',ctx,context_instance=RequestContext(request))
