How do I get a profile picture?

I feel like a noob for asking, but I really want to know!

How do you get a profile pic?

Thanks!

Click Settings (at the top right of the page), then scroll down to Edit Profile Picture (on the left hand side), then either choose option 1: enter a website or option 2: upload from your computer.

Remember max size is 100 by 100 pixels or 64.0 KB.

Thanks!

Im not sure if the photo im tryin to use is more the 64kb but it tells me :ERROR ENTITY ID UNKNOWN OR SOMETHING SILLY LIKE THAT

Do you mean avatar?
