Hello Joel! I'm Kris and I'd be happy to help you with your question.

Unfortunately, you are unable to use a custom gamerpic for a child account. Only adult accounts can. Please see the link below.

meant to ask on this account not that one

Hi there! This is Ronnie, an independent advisor.

Nice to meet you and I hope you are having a great day!

I understand you need help in changing your gamer picture from your PC.

You can actually do this using the Xbox companion app, if you do not have the app yet on your PC, please download this app from the Microsoft store.

Once you open the app, sign in to your account.

Once signed in, Click on your current profile image on the left side of the app.

Click Customize on the next page.

Click on the big circle where the picture should set to customize your gamer picture.

Then click on choose a custom picture. You should be able to select the image you want to add to your gamer picture.

Hope that helps!

Now there restricting people's accounts, I can't even change my gamerpic and it's doing my head in.

nobody available to talk to about this so looks like I'm stuck with it...

It's not account specific.
