Welcome to steemit, it can be a bit overwhelming t the start but it has a wonderful sense of community and you will find your way quickly,
I did my profile photo a couple of years ago and forget how i did it plus are busy at work at the moment so cant check how it is done but hopefully someone can give you some tips
Thank you! Going to have a look again now.
If you have any issues check out this post someone did a couple of years ago
