You could try if faster than you'll get an answer here, but, yes, you could do that. You may even want to set up a variable called $IMAGE_ROOT and set it to $_SERVER['DOCUMENT_ROOT'] in a config/include file, so that if you ever want to move all your images somewhere else, you only change one line of code. How's that going to help when the OP is using a *file path* as an image source ? Because if he tries it, he'll find out it wont' work. And if he has it only ONE place to fix, then that's better than having it all over his site, once he finds out that DOCUMENT_ROOT is wrong, but something like HTTP_HOST is right. -- Some people have a gift link here.

You don't need anything other than the first slash and it will be from the root of the web site. So all you need is: $url = '/images/holder.gif'; and it will come from http://whatever.com/images/holder.gif That actually relies on the browser to fill in the domain, and it's a Documented Feature so that's fine... But if you have dreams of scaling up to zillions of users, setting this up right so that you can flip all your images to separate boxes (or dcn or akami-like or...) is probably a Good Idea. It will only take a few minutes' work, and some discipline on an ongoing basis, but it's not hard by any means. -- Some people have a gift link here. Know what I want?

Re: [PHP] linking to an image with document_root
Hi,
You cannot use document_root to get the paths for images. You can write a
function to get the images url in your application.
function imageServer()
{
return /images/;
}

An image source is the URL to that image.
The server document root is the local location of that file (eg
/home/user/file.gif) - which is never going to work as a URL.

there are no stupid questions, only stupid answers.
$img_url= $_SERVER['DOCUMENT_ROOT'].'/images/holder.gif';
no you cant;
do this in a script on your server:
echo pre;
print_r($_SERVER);
and have look at the variables you can make use of, I would imagine
$_SERVER[SERVER_NAME] might be the ones you want.
clive
echo img src=\$img_url\ width=\250\ height=\163\/;
I am certain the path is correct,
If not what are my alternatives?
R.
