I would be a bit wary of a django blog making use of template tag.
Anyway, I believe your code should be more like that: {{
post.images[2].image.url }}.
Personally, I would delegate fetching the url to another part of the code.
Something like one endpoint would return a list of images. A piece of
javascript query that list and store it. When the user press a button,
put an image tag at the cursor position.
Or I would write a custom tag which would be used like {% image 2 %}
and would return the url of the second image of the current post.
