django - Accessing model instances associated with a forms.ModelMultipleChoiceField from the templates -

i'd create form allow visitor pick 1 or several instances of model looks this:

class package(models.model):                                                                                                                          name = models.charfield(max_length=255)     image = models.imagefield(upload_to="foo") 

i have created form looks this:

class packageselectionform(forms.form):     packages = forms.modelmultiplechoicefield(queryset=package.objects.all(), widget=forms.checkboxselectmultiple()) 

now, i'd display image associated each package instance in html form in respective label tags (or near), can't manage find way access instances form fields.

do see how can?
