Okay, so I have the Inkhorn Theme (http://inkhorntheme.ptcampbell.me/) installed on my Tumblr blog; but I want to insert an 'I Pledge To Read The Printed Word' image on it.
I'd like it to be in the little description 'box' above my information, but underneath the line below the title. Where do I post the code for this to happen?

Note: The blog in question is http://wedinewithdisaster.tumblr.com/

Thanks!
