Welcome Nalini!
As soon as I read the title I'm like "that sounds like someone I'll be following" and the more I read, the more I loved it!

I needed to search the FAQS section to figure out how to upload a profile picture haha, so here's the link below:
-follow link
-upload photo
-click photo
-copy link of photo
-paste in profile pic bar in the settings section of your steemit profile
-link - https://imgsafe.org/

Hope this helps!! :D
