title: HTML Email Signature on iOS - Images are not displaying.
body: <p>I have created an HTML email signature using the usual tables and inline styling.</p>
  
  <p>There is also one image attachment of a logo. It displays perfectly in all email clients.</p>
  
  <p>However when I try and make an iPhone/iPad signature I have problems:</p>
  
  <p>The image displays ok, for a couple of hours and then just drops away and a little box with a cross displays instead.</p>
  
  <p>Does anyone have any ideas why this might be?</p>
