title: How can I place a photo on someone else's webpage when linked to from my site?
body: <p>I know this is a strange thing to want to do, but...</p>
  
  <p>How can I place a photo at the top of someone else's webpage ("Page B") -only- when a visitor links there from my page ("Page A")?  I have permission to do this, but with certain limitations: my code needs to be in one location on Page B, and I can't make major changes to Page B.  I cannot use Page B's server to run PHP, but I can run PHP on Page A's server.</p>
  
  <p>The photo needs to open automatically with the rest of the Page B, and not require any user input to show up.</p>
  
  <p>This is a unique vendor/retailer situation, so unfortunately I can't provide the urls.</p>
  
  <p>Thanks for any help.</p>
