Jeremy,
Extending a template do not magically gives you access to the context
variables the other template has.
The context is set in the view, what's the view for the homepage? You
didn't include it in your post.
Is the variable images set in there? I recommend using django debug toolbar
to help debugging issues
like this.
Anyway, make sure to set a context variable `images` in your homepage view
and you will be all set.
