Ah, nevermind. If I just tap lightly on the Camera icon, it shows a choice between Camera and Saved Photos! Worked fine. For some odd reason, the first time I tapped Camera, it just asked to access the Camera, and didn't offer the choice.
I'm having the same difficulty as tfy9148 above. Unfortunately, Brian's solution doesn't help as there isn't any icon that looks like a picture frame to the right of the camera icon within the note.
