How do I turn off pictures from auto saving into my camera roll from my iMessages?

Thanks for reaching out rbells,

Once you've taken a screenshot, tap it to bring up the Photo editing options. You should see the Share button at the top right corner. Select where you want to share it to, then send it. Once it's sent, your iPhone screen should return to the previous Photo editing page. You can delete it there before it reaches the Photos app.

If you miss the opportunity, you can locate all of your screenshots in the Photos app under Albums > Media Types > Screenshots to delete them there.

Take care.

I have this same problem but not with screen shots, it’s photos. I don’t want them saving automatically to my camera roll.
