[FMX04] Newbie question: Loading external vars

I have this bit of code in my flash document:

loadVariables("album.php", this, "GET");
this.pathToPics="images/projecten/";
var BlaBla = "IMG_0138.JPG";
loadMovie(this.pathToPics+BlaBla, _root.ImportImage);

What does this do?
_root.ImportImage is a graphic in my flash document.
It just loads an external image into the graphic…
var BlaBla is a temp variable to show what the problem is.
The code here above works, but i want to load ImageName from the php file.

My php file looks like this:

<?php
 echo 'ImageName=IMG_0138.JPG
      &ImageInfo=Geen Omschrijving';
?>

This is what it i tried (look at ImageName in php and here under…):

loadVariables("album.php", this, "GET");
this.pathToPics="images/projecten/";
loadMovie(this.pathToPics+**ImageName**, _root.ImportImage);

Without succes…
Could anyone help me?
