        """Use this method to send photos.

        Args:
            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).
                For a private channel/supergroup you can use its *t.me/joinchat/* link.

            photo (``str``):
                Photo to send.
                Pass a file_id as string to send a photo that exists on the Telegram servers,
                pass an HTTP URL as a string for Telegram to get a photo from the Internet, or
                pass a file path as string to upload a new photo that exists on your local machine.

            caption (``bool``, *optional*):
                Photo caption, 0-200 characters.

            parse_mode (``str``, *optional*):
                Use :obj:`MARKDOWN <pyrogram.ParseMode.MARKDOWN>` or :obj:`HTML <pyrogram.ParseMode.HTML>`
                if you want Telegram apps to show bold, italic, fixed-width text or inline URLs in your caption.
                Defaults to Markdown.

            ttl_seconds (``int``, *optional*):
                Self-Destruct Timer.
                If you set a timer, the photo will self-destruct in *ttl_seconds*
                seconds after it was viewed.

            disable_notification (``bool``, *optional*):
                Sends the message silently.
                Users will receive a notification with no sound.

            reply_to_message_id (``int``, *optional*):
                If the message is a reply, ID of the original message.

            reply_markup (:obj:`InlineKeyboardMarkup` | :obj:`ReplyKeyboardMarkup` | :obj:`ReplyKeyboardRemove` | :obj:`ForceReply`, *optional*):
                Additional interface options. An object for an inline keyboard, custom reply keyboard,
                instructions to remove reply keyboard or to force a reply from the user.

            progress (``callable``, *optional*):
                Pass a callback function to view the upload progress.
                The function must take *(client, current, total, \*args)* as positional arguments (look at the section
                below for a detailed description).

            progress_args (``tuple``, *optional*):
                Extra custom arguments for the progress callback function. Useful, for example, if you want to pass
                a chat_id and a message_id in order to edit a message with the updated progress.

        Other Parameters:
            client (:obj:`Client <pyrogram.Client>`):
                The Client itself, useful when you want to call other API methods inside the callback function.

            current (``int``):
                The amount of bytes uploaded so far.

            total (``int``):
                The size of the file.

            *args (``tuple``, *optional*):
                Extra custom arguments as defined in the *progress_args* parameter.
                You can either keep *\*args* or add every single extra argument in your function signature.

        Returns:
            On success, the sent :obj:`Message <pyrogram.Message>` is returned.

        Raises:
            :class:`Error <pyrogram.Error>`
