How to get an dictionary item in template

[BigBlogMaker]

I'm sorry for my english, but on other groups nobody does not answers.

In view defined variables:

production = Production.objects.all ()
images = {}
for product in production:
try:
image = product.image_set.get (somefield = somevalue)
images [product.id] = image
except:
pass

Now the question is: how to access the elements of images in the
template?

{% for product in production %}
{{ product.title }}
{% if images %}

{% endif %}
{% endfor %}

Each product can have multiple images.
images are divided by type. it facilitates the withdrawal of the
desired image in the right place.

Filtering related objects in template

[BigBlogMaker]

Can I filtering of related objects in a template? Explained:
Now I make so

{% for image in product.image_set.all %}
{% if image.image_type.id == 777 %}

{% endif %}
{% endfor %}

And I would like to:

{% for image in product.image_set.all | image_type.id : 777 %}

{% endfor %}
