Q: My iphone 6s is not receiving text with pictures, since the update IOS 10.0.2

Just text with pictures, or iMessage and pictures too? A text with pictures is an MMS, and you need to make sure that MMS is turned on in settings and that cellular data is also turned on. SMS/MMS are controlled by the carrier, and you may need to check with them if you have those settings turned on and are still having issues. They may need to reset your SMS/MMS plan.

If you are having issues with an iMessage with picture, then you need to make sure your data is on, either cellular or wi-fi, depending on what you are connected to. Also check Settings>Messages, and make sure that iMessage is activated.
