sign up to https://en.gravatar.com/

then you upload your picture you wanna use to that....then set it to PG when it asks for a rating

then go back to battlelog and put in your gravatar email in you prefrences where it says change avatar

battlelog and EA are seperate, so one will not do the other

for EA (origin chat) you just edit your profile and in there is where you can change it
