Need Help On Steam

All right, everyone. What’s up? This is my first post in this forum. Moreover, I am not sure if this is the right place to post this. But I hope I will get a better suggestion from you. I am experiencing an issue with my Steam account. That is, I cannot upload images (such as the chatbox or profile picture). Can anyone tell me why this is happening?

Could be that your steam browser is out of date and needs updating or family settings on your steam that prevent such content.
