CakePHP Absolute Image URLs

cakephp, url

Solution

In CakePHP 1.x the method is:

$this->Html->image($this->Html->url('/path_to_image/image.png',true));

In CakePHP 2.x the method is:

$this->Html->image('/path_to_image/image.png', array('fullBase' => true));

Problem

I wish to use the `$html->image(...)` helper function in CakePHP to output images, but I need it to produce an `img` tag using an absolute rather than relative URL (the resulting HTML will be downloaded and emailed round in a company newsletter). Is this possible? It's not documented, but I notice from looking at the source code that the `image` 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 `webroot/img` folder.
