Question

hi all
im kinda new to this
i have 1 pic i want to place in specific coordinate
i opened up a new document A4
and i opened my script
i have a problem with the x and y coordinate
the numbers doesnt make sense
what i did?
i manualy checked for the x and y coordinate
i wrote them down in the script but i didnt came in the place it suppose to be
any idea? im working with pixels and i set up it work also in pixels
here is my code:
thanks!
file = app.openDialog();//opens dialog,choose one image
var doc = app.activeDocument;
for (i=0;i<4;i++) {
    app.load(file[0]); //load it into documents
    backFile= app.activeDocument; //prepare your image layer as active document
    backFile.selection.selectAll();
    preferences.rulerUnits = Units.PIXELS; // tell ps to work with pixels
    backFile.selection.copy(); //copy image into clipboard
    backFile.close(SaveOptions.DONOTSAVECHANGES); //close image without saving changes
var width =850; //width of image
var height = 1100;  //height of image
var x =0; //x pos
var y =0; //y pos
    selectedRegion = Array(Array(x,y), Array(x, width), Array(height,width), Array(height, y));
    doc.selection.select(selectedRegion);
    doc.paste(); //paste selection into your document
    doc.layers[i].name = i; //set your layer's name

Update my script to enable you to paste into more the one column.
