Adding photos to iPhone 7 text Messaging

[JGVillages]

I have the iPhone 7 with ios10. When I go to Messaging to create a text message I have a camera icon at the bottom where I assume photos can be added, but the camera icon and 2 others are "graced out" so I cannot use them. Cannot figure outb how to correct this. Any help would be appreciated.

Make sure you have entered an address in the TO: first. It won't let you access adding photos until you've done so!

That did it. Thanks.
