How can I know when the third multiple is reached in an arbitrarily long list

[Jason]

Hi there,

I'm trying to put together a photo album using django client side and I want to align the photo's 3 in a row. In order to do this I'm putting the photo's in a table (not ideal I know...) and I was wondering how I can have a table row with 3 images only? Right now my table just puts a bunch of photos in a row but I cannot figure out how to start a new row after 3 images have been put in. 

Any ideas would be appreciated.

What I've got so far is:

<h1>{{the_adventures.adventure_name}} <small>{{the_adventures.adventure_date}}<small></h1>

    <table>

        <tr>

        {% for photo in the_adventures.the_photos %}

            <td>

                <img  height="100px" width="100px" src ="/serve/{{ photo.blob_key.key }}">

            </td>

        {% endfor %}

        </tr>

    </table>

<a href = "/view_album/{{the_adventures.adventure_name}}/{{the_adventures.adventure_date}}/{{the_adventures.cursor}}">Next page</a>

What I want is:

image image image

image image image

image image image

etc

You can use the divisibleby template tag in combination with a
forloop.counter (both explained on this page):
