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!
