Changing Background Picture In Lodestone

My character profile has that pumpkin background, how can I change it to the Grand Company Background I have?

I've tried going
Profile > Character Profile for Artemys Knight (Lindblum)
there I have 3 images I can click on but it doesn't change the picture, can it be changed?

I've been told you can change it, but I'd like to know as well.

1. log into lodestone (by the green "log in" button on main page)
2. the green "log in" button turns into a brown "My site" button, click that.
3. on your profile below your current profile picture there are thumbnails of what you have available.
4. click the one you want.

edit: hmmm I just tried it myself and I swore you could be able to do it but it just switches back. I think the lodestone automatically choose the event themed ones for the duration. Hovering the mouse over the thumbnails shows the larger ones but it doesn't change it.

Yea that's what I originally thought but got the same results, I wasn't sure if I was doing it wrong or if there was no current way to change it.
