What is the ruling on sending a picture of a veiled girl, wearing a wedding dress with her hair and back uncovered, to her male cousin without her knowledge?

Photographing women and circulating their images carries risks, as they might fall into the hands of those who are not permitted to look at them. If the image was sent without your knowledge, there is no sin upon you, but you must strive to ensure that the person to whom the image was sent disposes of it.
