Voting banner question

I just recently got verified as a web novel on the fiction guide here and I was wondering if anyone knew how to add a banner to their voting page? I am sure it will take a little to get where I actually appear high enough to be seen, but I want to try to get ahead of the game at least a little bit.

There's a few email addresses you can send it to ([email protected], [email protected] [email protected] [email protected]) However, I sent in updated banner art for Not All Heroes about a month ago (to all of the email addresses) and it hasn't been adjusted yet.
