Easiest possible way to upload profile picture & cover image??

Hi my fellow Steemit friends,

Can anyone state in plain terms how they upload a profile picture and cover image to their Steemit account??

I don't know whether I have done this correctly?

I have tried around 3 or 4 different sites, doesn't seem to work in any of them.

Am sure this doesn't has to be that difficult?

Would appreciate your assistance very greatly!!

Kind regards,

Taz
