"""Get a list of profile pictures for a user or a chat.

Parameters:

chat_id (``int`` | ``str``):

For your personal cloud (Saved Messages) you can simply use "me" or "self".

For a contact that exists in your Telegram address book you can use his phone number (str).

Sequential number of the first photo to be returned.

By default, all photos are returned.

limit (``int``, *optional*):

Limits the number of photos to be retrieved.

Values between 1—100 are accepted. Defaults to 100.

Returns:

List of :obj:`~pyrogram.types.Photo`: On success, a list of profile photos is returned.

Example:

.. code-block:: python

# Get the first 100 profile photos of a user

app.get_profile_photos("haskell")

# Get only the first profile photo of a user

app.get_profile_photos("haskell", limit=1)

# Get 3 profile photos of a user, skip the first 5

app.get_profile_photos("haskell", limit=3, offset=5)
