Hello! Welcome to Steemit!
To upload a photo, go to your settings and you will need to provide a link to your selected profile picture.
You will need to upload a photo of yours to a hosting site, such as google.com/photos. This is free and easy to set up and use!
Then just link your profile picture in your profile settings and you're all good to go!
Have fun Steeming!
Thanks fam. I figured out the commenting part too ✌️
