title: CakePHP Absolute Image URLs
body: <p>I wish to use the <code>$html-&gt;image(...)</code> helper function in CakePHP to output images, but I need it to produce an <code>img</code> tag using an absolute rather than relative URL (the resulting HTML will be downloaded and emailed round in a company newsletter). Is this possible?</p>
  
  <p>It's not documented, but I notice from looking at the source code that the <code>image</code> function can take an array as its first argument. It's not entirely clear to me how to get this working though - a naive attempt to do it this way produces image URLs relative to the current page rather than within the <code>webroot/img</code> folder.</p>
