The profile photo is your headshot that appears on your channel homepage. It is also used for credits and other references to your channel.
Adding a profile photo
On the Channel Overview page, click ‘Customize channel photos’.
Click ‘Pick profile photo’.
The profile photo should be a square. If it is longer on any side it will be cropped. In other words, we will not letterbox or pillar box (black bars) the image. The recommended resolution is 600 x 600.
Remember to click ‘Update channel photos’ after you are done!
