Hey there.
I am running a simple installation with some modules to support multi language. The negotiation happens on the first path argument: translated contents are at /en/node/1, en/taxonomy/1, etc, and this is ok.

I have problems while generating urls to resources such as images:

<?php
print url("sites/all/themes/my_theme/img/my_image.png")
?>

would result in http://drupal_root/en/sites/all/themes/my_theme/img/my_image.png, and the image doesnt exists in that location.

How to approach this matter?

Thank you.
