"""Get a list of profile pictures for a user or a chat.
Parameters:
chat_id (``int`` | ``str``):
Unique identifier (int) or username (str) of the target chat.
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).
offset (``int``, *optional*):
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
