This is the expected result. $_SERVER['DOCUMENT_ROOT'] is just that. The path from root of the _filesystem_ to where Apache's document root is. This is not Apache's document root. What you're looking for above is something like $_SERVER['HTTP_HOST'] or $_SERVER['SERVER_NAME']. I'd stick with HTTP_HOST, something like this... echo ( "<img src=\"http://" . $_SERVER['HTTP_HOST'] . "/path/to/image.jpg\">";

Of course, the first instance only works if the script is in the correct place relative to the /inline directory. However, the second case fails if I use it in the following function (assuming I specify $dir as "/inline"). It returns a false result, as if it couldn't find the directory.

This is where you would want to use DOCUMET_ROOT. -- By-Tor.com ...it's all about the Rush http://www.by-tor.com
