To only download Instagram pictures (and metadata) that are within a specific

period, you can simply use :func:`~itertools.dropwhile` and
:func:`~itertools.takewhile` from :mod:`itertools` on a generator that returns
Posts in **exact chronological order**, such as :meth:`Profile.get_posts`.

Discussed in :issue:`121`.
The code example with :func:`~itertools.dropwhile` and
:func:`~itertools.takewhile` makes the assumption that the post iterator returns
posts in exact chronological order. As discussed in :issue:`666`, the following
approach fits for an **almost chronological order**, where up to *k* older posts
are inserted into an otherwise chronological order, such as an Hashtag feed.
