problem sending messages

Hello.
The problem is that when I send a message to another user, only the text is sent, but they don't see the copied and pasted image, even though everything is clearly visible in my message.
I tried it twice, so it can't be a random fluke.
I'm attaching a screenshot.

Hello,

Are you trying to send a picture in messages? I don't think that's going to work... I haven't tried it myself, anyway.
