Answer 1

Just make your own Input class and alter the render callable to whatever you want. As an example, here's one I made to add in a little avatar. It's quick and dirty, in that it's not DRY, but it serves a purpose:

class AvatarInput(ClearableFileInput):
'''renders the input file as an avatar image, and removes the 'currently' html'''

template_with_initial = u'%(initial)s %(clear_template)s
%(input_text)s: %(input)s'

def render(self, name, value, attrs=None):
    substitutions = {
        'input_text': self.input_text,
        'clear_template': '',
        'clear_checkbox_label': self.clear_checkbox_label,
    }
    template = u'%(input)s'
    substitutions['input'] = super(AvatarInput, self).render(name, value, attrs)

    if value and hasattr(value, "url"):
        template = self.template_with_initial
        substitutions['initial'] = (u''
                                    % (escape(value.url)))
        if not self.is_required:
            checkbox_name = self.clear_checkbox_name(name)
            checkbox_id = self.clear_checkbox_id(checkbox_name)
            substitutions['clear_checkbox_name'] = conditional_escape(checkbox_name)
            substitutions['clear_checkbox_id'] = conditional_escape(checkbox_id)
            substitutions['clear'] = CheckboxInput().render(checkbox_name, False, attrs={'id': checkbox_id})
            substitutions['clear_template'] = self.template_with_clear % substitutions

    return mark_safe(template % substitutions)

Then just drop it into your form class Meta:

    class Meta:
        model = 
        widgets = {'your-field-name': AvatarInput()
