I am trying to put together a script that will detect pages that have 2 types of elements.

1. blank graphic frames
2. graphic frames with images larger than the frame holding it.

I've created a simple 5 page doc and placed images on page 1 and 3. So the frist step is can I flag that page 1 and 3 have image on them.

This is what I have so far

var myDoc = app.activeDocument;
var myPages = myDoc.pages;
var myRecs = myDoc.rectangles;

for (var j = myPages.length - 1; j >= 0; j--) {
	if(myPages[j].rectangles.length >= 1){
	$.writeln("page "+j+" has a frame.");
	}
}

And it returns the following in the console which is correct.
page 2 has a frame.
page 0 has a frame.

Is there a way to check if the frame has an image and if it image fits the frame or not?
