Finding a list of elements in Javascript

I've created a function that creates a new img and puts it in every tag which has the css class "painted":

function putPiece(){
    var painted = document.querySelectorAll('.painted');

for (var i = 0, len = painted.length; i < len; i++) {
    var a = i+1
    var squareID = painted[i].id;
    painted[i].taken = 'BP'+a;

    var img = document.createElement("img");
    painted[i].appendChild(img);
    img.id = "BP"+a; //unique ID for every img
    img.src = "blackP.png"; //the image to use
    img.pstn = squareID; //the ID of the <td> it's in


}
}

Iv'e given properties to each object, as noted above. Now I would like to create an array that would contain the "img.pstn" of all the "img" objects. Any ideas? thanks ahead!

Create an empty array outside the loop, and at the bottom of the loop just add:

arr.push(squareID);
