Click on the arrow beneath choose command from (1), and on Commands not in the ribbons (2).
Scroll down the alphabetic order to C, and click on camera (1), then press add (2), and ok.
Click on the cell that you want to create picture of.
Click on the camera on top. You have a picture of the cell ready.
In conclusion, unfortunately, you can only use the camera tool to take a picture of a cell, but not a chart. I know this, because I tried.
