I get text sometime and my screen is locked bet the message or pics shows on the locked screen is there a way to stop this

Try Settings > Notification Centre and change the settings for Messages (under the 'Include' headig) e.g. 'show on lock screen' to 'off'

Try settings> notification center> scroll down to Messages> show on lock screen> off.

Or, you can just turn of the preview. Settings>Notifications>Messages>Show Preview. Then, only the contact from whom the message is being sent will show.
