If you go to my pet's profile, you'll see that I used a premade one. I like a lot and have been searching around to figure out how to make really minor changes like making the links visible (because originally they were so dark you couldn't read them) and repositioning the minion so it showed up in the "box" so to say.

BUT I was wondering if there was a way to make my pet's picture so there isn't a white box behind it. Can I make the white boxes for his minion and treasure go away too? Just wondering.

You can't remove the 'white boxes' with code. Those are actually part of the image so all you can do is open an image editing program and remove the white that way, or have someone else do it for you.

Before changing the code of a premade layout be sure that you have permission to do it! (it should say on the page where you got the layout if you can or not)

Oh! Thank you!
