iMessage sends screenshot name, date, time info in text above screenshot post

Greetings topdog417,

There are a few things to try on your wife's phone.

1. Ensure that the iOS is fully updated, since updates can often contain fixes: Update your iPhone or iPad
2. Restarting can also help so, Restart your iPhone.
3. If the issue continues, contact Apple Support for more guidance.

We hope this helps!

Sincerely.
