Opt In Wordpress Plugin - How to design around the restrictions

We are using the Wordpress Plugin - Infusionsoft Opt In and find it restrictive.
Is there an add on or update that makes it more dynamic?

We would like to:

  • use our own images on the Opt Ins without them being resized and bordered.
  • change text size, font, etc
  • play with the design to make it dynamic
  • place the inline or stacked optin where we want.

I’ve attached an pic similar to what we’d like to create.
