Steemit uses the profile image from my Twitter profile, but DTube has trouble accessing that for some reason. I've read some saying that it can take "a while" for Steemit profile to sync with DTube but it's been weeks and still no profile image on my DTube account. It's a shame because a blank profile image is probably the first thing people see looking at your profile and deters many from following. I personally would never follow an account if they haven't bothered to set up their profile. I hope Steemit and Dtube figure out this glitch soon.
