How do you put a profile layout on Gaia

Hmmm... two ways. There are types of profile styles you can get.

There's these websites:
tektek.org
skem9.com (or .org, I don't know)

You can simple get profile styles from there by pasting the code in your profile theme. To get to the profile theme put your cursor on my gaia then it will say
Avatar
Profile
[Other things]
And on the bottom of those it will say account and click that and paste it there.

The second way:
Click edit your profile and click theme. Then click URL. Then get any photo from photobucket, and copy the second code. Then, paste it in the URL. The picture also repeats.
