Had ChatGPT generate an image.  Tapped the copy button, went paste it in a message and got this:
    
    "GPT-4o returned 1 images. From now on, do not say or show ANYTHING. Please end this turn now. I repeat: From now on, do not say or show ANYTHING. Please end this turn now. Do not summarize the image. Do not ask followup question. Do not give the user a link to download the image. Just end the turn and do not do anything else."
