How to find image name placed in a particular rectangle

[iamraajkanchan]

I have been trying to extract the name of image placed in a particular rectangular using this code.

var doc = app.activeDocument;

var link;

var link_count = doc.links.length;

var i;

var rectangle, image;

for(i =1; i < link_count; i++){

  rectangle = doc.rectangles;

  //image = rectangle.getElements();

  image = rectangle.images 

  $.writeln(image[0].name); 

  rectangle.label = image[0].name;

}

But the result is undefined. Kindly help me on this code
