Problem with cameras/Megapixels?

[Eugo]

Few hours later, I still can't get it done. I assumed I put the scripts in the protected area where they are a bit unusable, so I put them into a folder below ~/Downloads. Trying to run „sudo ./setup.sh“ detects root and refuses to run, says „Script must not be ran as root“. When running as manjaro, it reports
chmod: мењам овлашћења за „'/home/manjaro/.config/megapixels/postprocess.sh'“: Радња није допуштена
(changing authorization for ... operation not permitted)

So... what am I doing wrong?
