How to adjust the camera and merge it with the gallery view

Bear with me as I'm Deaf so English / Explaining what i'm trying to do 

Basically what I'm trying to do is disable the pop up but merge my camera into gallery view 

as you can see from the image, my camera is on the top left corner and i want it to be in the Gallery so that its easy to see myself while talking to multiple Deaf users 

I hope i make sense?
