Answer 1

Accoding to example you can sendPhoto:

await Bot.SendChatActionAsync(message.Chat.Id, ChatAction.UploadPhoto);

            const string file = @"<FilePath>";

            var fileName = file.Split('\\').Last();

            using (var fileStream = new FileStream(file, FileMode.Open, FileAccess.Read, FileShare.Read))
            {
                var fts = new FileToSend(fileName, fileStream);

                await Bot.SendPhotoAsync(message.Chat.Id, fts, "Nice Picture");
            }

Answer 2

The problem can be originated from the following issues:

• the image file extension is not allowed by the telegram.
• file size is larger than that allowed by the telegram.

You can start with the former one.
