Change link on img in template using forms

[Dariusz Mysior]

How in template.html change link <a> on <img>.

<p><label for="id_avatar">Zdjecie:</label> Teraz: <a href="/media/avatar/n.jpg">avatar/n.jpg</a>

In forms.py like below I see that I can change label name, but how can I do this with <a> ???

class MysiteUserForm(forms.ModelForm):
    #age = forms.IntegerField(min_value=1, max_value=99, widget=forms.NumberInput(attrs={}))
    #avatar = forms.ImageField()
    class Meta:
        model = MysiteUser
        fields = ['sex','age','province','city','martial_status','religion','kids','education',
                  'are_smoke','are_drink','avatar']
        labels = {
            'avatar': _('Zdjecie'),
        }
