Filtering images from the selection

Question

I am writing a script that involves scaling and sorting images. Which means i have to access the geometricBounds property of the images. Now, when the selection contains either an EPS or PDF file the script fails.
So i am trying to filter through the selection array to find images that are NOT EPS or PDF. I noticed that EPS and PDF files don't have geometricBounds. So i was trying to use that property to sort it. But i am running into issues. Any thoughts? Solutions?
if(app.documents.length != 0){
  if(app.selection.length != 0){
  for(myCounter = 0; myCounter < app.selection.length; myCounter++){
  switch(app.selection[myCounter].constructor.name)
  case "GraphicLine":
  case "Oval":
  case "Polygon":
  case "Rectangle":
  if(app.selection[myCounter].contentType != ContentType.UNASSIGNED){ // checks to make sure frame contains an image.
     if(app.selection[myCounter].graphics[0].geometricBounds[0]) { // checks to see if image has a width property. else it avoids it.
           myObjectList.push(app.selection[myCounter]);
  break;
  if(myObjectList.length !=0){
                    openDialog(myObjectList, keyObj);
  // moveItems(myObjectList);
  } else {alert("Select some images, fool!")}

Hi,
Both do - check Object Model.
Looks like there is another reason as your script fails. Cant say more without details.
Notice that PDF and EPS is a standalone class (alike Image is) ==> so one does not include another.
