How to identify highlighted images in javascript

[cutch2222]

Sorry for the newbie question. I have a script that creates stacks by capture time for all images in a folder.

I'd like to be able to run it only on the highlighted images. I'm just not sure how to identify a highlighted image in javascript.

Thanks

This is from Edit Script Add Pictures eliminated the dialog box

#target photoshop;
alert(GetFilesFromBridge().join('\n'));
function GetFilesFromBridge() {
function script(){
var fL = app.document.selections;
var tF=[];
for(var a in fL){
    if(fL.type =='file'){
        tF.push(new File(encodeURI(fL.spec.fsName)));
        }
    }
return tF.toSource();
}
  var fileList;
  var bt = new BridgeTalk();
  bt.target = "bridge";
        bt.body = "var ftn = " + script.toSource() + "; ftn();";
  bt.onResult = function( inBT ) { fileList = eval( inBT.body ); }
  bt.onError = function( inBT ) { fileList = new Array(); }
  bt.send(8);
  bt.pump();
  if ( undefined == fileList ) fileList = new Array();
  return fileList;
};
