About pictures for characters, you have three options.
You can add pictures to your summary page by using bbcode [ img] LINK HERE [ /img]
Except without the spaces in between the first square bracket and the "img" I just put that there so that it would show up. I don't know if it would otherwise. You put it in the "Description" part of your "Edit Story".
You can also use it in the story chapters if you want.
And at your "My Mibba" page there is a spot along the side under the label "Stories" where it says "Characters" and you can add stuff there too. There you can use pictures from your computer rather than having to use a link from photobucket or something.
Talk to me or ask me questions if you want. And thanks for commenting on my story, Boring Title That Doesn't Interest You :)
I think you deserve a hug
