I cannot figure out how to get the picture I want as my profile to fit for the life of me

I literally created this account simply because I did NOT want my friends knowing I'm writing something and I know if I published the prologue on their they'd know and I don't need that embarrassment lol

I've been a known user of Wattpad for so long that I'm ever so slightly disappointed I can't release this prologue on the account where I have actual fans just cause I don't want my friends to know until I've finished like the first book
