You are loading your document with $dompdf->load_html(). Because of this dompdf does not know where your document lives and assumes all paths that do not include a domain are referencing files on the local file system. Absolute paths are from the root of the file system; relative paths are relative to the location of the PHP script using dompdf.

With the above in mind ... your images are included using the image function (e.g. $this->Html->image('logo.png'); ?> which outputs a path similar to /images/logo.png. dompdf sees this path and looks for the file from the file system root (instead of, for example, /inet/www/siteroot/images/logo.png).

The easiest method of resolving the issue would be to tell CakePHP to include the domain, e.g. $this->Html->image("logo.png", array('fullBase' => true));.
