+=============================

+.. currentmodule:: instaloader
+
+.. highlight:: python
+
+.. contents::
+   :backlinks: none
+
+Here we present code examples that use the :ref:`python-module-instaloader` for

+interface.
+
+.. For each code snippet:
+   - title
+   - brief description of what it does / motivation / how it works
+   - code, or link to code
+   - link to discussion issue
+   - link used methods
+
+Download Posts in a specific period
+-----------------------------------
+
+To collect pictures (and metadata) only from a specific period, you can play
+around with :func:`~itertools.dropwhile` and :func:`~itertools.takewhile` from
+:mod:`itertools` like in this snippet.
+
+.. literalinclude:: codesnippets/121_since_until.py
+
+See also :class:`Post`, :meth:`Instaloader.download_post`.
+
+Discussed in :issue:`121`.
+
+Likes of a Profile / Ghost Followers
+------------------------------------
+
+To store inactive followers, i.e. followers that did not like any of your
+pictures, into a file you can use this approach.
+
+.. literalinclude:: codesnippets/120_ghost_followers.py
+
+See also :meth:`Profile.get_posts`, :meth:`Post.get_likes`,
+:meth:`Profile.get_followers`, :meth:`Instaloader.load_session_from_file`,
+:meth:`Profile.from_username`.
+
+Discussed in :issue:`120`.
+
+Track Deleted Posts
+-------------------
+
+This script uses Instaloader to obtain a list of currently-online posts, and
+generates the matching filename of each post. It outputs a list of posts which
+are online but not offline (i.e. not yet downloaded) and a list of posts which
+are offline but not online (i.e. deleted in the profile).
+
+.. literalinclude:: codesnippets/56_track_deleted.py
+
+See also :func:`load_structure_from_file`, :meth:`Profile.from_username`,
+:meth:`Profile.get_posts`, :class:`Post`.
+
+Discussed in :issue:`56`.
+
+Only one Post per User
+----------------------
+
+To download only the one most recent post from each user, this snippet creates a
+:class:`set` that contains the users of which a post has already been
+downloaded. When iterating the posts, check whether the post's owner already is
+in the set. If so, skip the post. Otherwise, download it and add the user to
+that set.
+
+.. literalinclude:: codesnippets/113_only_one_per_user.py
+
+See also :class:`Post`, :meth:`Instaloader.download_post`,
+:attr:`Post.owner_profile`, :class:`Profile`.
+
+Discussed in :issue:`113`.
+
+Upgrade Images by local Copies
+------------------------------
+
+The following script finds local versions of images fetched by Instaloader, in
+order to ugprade the downloaded images by locally-found versions with better
+quality. It uses image hashing to identify similar images.
+
+`updgrade-instaloader-images.py <https://gist.github.com/pavelkryukov/15f93d19a99428a284a8bcec27e0187b>`__ (external link to GitHub Gist)
+
+Discussed in :issue:`46`.
+
+Render Captions to downloaded Images
+------------------------------------
+
+Instaloader does not modify the downloaded JPEG file. However, one could combine
+it with an imaging library such as Pillow or PIL to render the
+:attr:`Post.caption` on pictures.  The following shows an approach.
+
+.. literalinclude:: codesnippets/110_pil_captions.py
+
+See also :attr:`Post.caption`, :attr:`Post.url`, :meth:`Post.from_shortcode`,
