why so many users on steemit do not have a profile picture?
its because not everybody visits the FAQ page on steemit and some of those that do visit dont pay more attention to details
and as a result almost 90% of the new users on steemit do not have a profile picture, bot that they don't want to have one, they just don't know where to do that...

My reasons for this sugestion
*1. to make the site more user friendly

1. Easy access to the postimages.org website
2. creates more familiarirty for the postimages.org websites, as u get to see it anything you visit your settings
3. Makes it easy for users to change their profile picture and cover image anytime they wish
4. making life easy for steemians
