title: Mail chimp with Devise and Rails
body: <p>I'm trying (failing miserably) to setup mandrill/mailchimp to work with rails 4 and devise.</p>
  
  <p>I'm having loads of trouble using dynamic fields, but now, i can't even insert my logo without mail chimp overriding it to put a black square background behind it. </p>
  
  <p>All I have done is import the image, then when I try to resize it in mailchimp, it imposes a black square background. </p>
  
  <p>Does anyone know how to block this background from being imposed?</p>
