ESP32_FTPClient Upload image from SD-CARD

Question

Hello everyone and sorry for the inconvenience. I encountered a problem when I try to copy a jpg image from the SD-CARD to the FTP area. The image is copied correctly but is unreadable. I attach the part of code that performs this operation. I would be grateful if you could help me solve the problem. Best regards.

I expected the image to be uploaded from SD-CARD to FTP. The name and size of the image in the FTP area correspond to the original photo but the content is:

00355/0355-20240212171954.jpg û?#�� #�� 150 Accepted data connection 205 40 38 195 160) em - No anonymous login 220 You will be disconnected after 15 minutes of in�´û?ø @? è� ��ý?`½ý?€ý?¨ý?�� ˆ� ø @? è� ”®ý?�ªý?°ªý?تý?� ˆ� � p_ü? _ü?Ô_ü?� �00355/0355-20240212171954.jpg û?#�� #�� 150 Accepted data connection 205 40 38 195 160) em - No anonymous login

I'm probably wrong with the parameters I supply to the function: ftp.WriteData but I don't know what else to give him.
