Is it possible?
Let's say my directory structure looks like this:
/data
/data/images
/public
The document root is in the "public" directory. This won't work, of course:
<img src="/../data/images/1.png" alt="" />
But maybe it's possible to enable serving images from directory above document root somehow? I would like to know.
The most common way is an Alias:
Alias /data/ /wherever/your/data/are/
Another way (say if you can't set an alias...) would be to use a script as the image source eg:
<img src="image.php?img=myImage.jpg" />
image.php would be similar to:
<?php
header('Content-Type: image/jpg');
readfile("../img/" . $_GET['img']);
?>
Of course you'd need to extend the script to filter $_GET['img'], as well as detect and set the right content type. Your script could even resize the image according to other parameters passed in the query string.
