As Dixon says, you should be more explicit in your code. When using
$dompdf->load_html() dompdf does not have any sense about your web site. Code loaded in this manner is assumed to not have a defined web presence and so links are relative to the operating system file system.
Alternately, you could provide a hint to dompdf that this is web-based content using the BASE tag. Though in order for this to work properly you will need to be using the latest code (available from the
SVN repository or as a
nightly download).
$theHtm = "<html><head><base href="http://site.com"></head><body>daata<img src='/images/069.jpg'/></body></html>"; There might also be a way to specify the base path using the dompdf object, though I'd have to investigate this further as I've had trouble with this functionality in the past.
