Javascript: get image size (width & height) for an array of multiple images

Question

How to adapt this solution (code from here: https://stackoverflow.com/a/626505/975443)

var img = new Image();
img.onload = function() {
  alert(this.width + 'x' + this.height);
}
img.src = 'http://www.google.com/intl/en_ALL/images/logo.gif';

for multiple images (for loop through an array)?

Answer 1

Solution:

var asyncI = 0;
var asyncCount = 10;

function readImageDimensions() {

    console.log('asyncI: ' + asyncI);

    var img = new Image();
    img.src = 'data/images/' + asyncI + ".png";

    img.onload = function() {

        console.log('this.width: ' + this.width + ', this.height: ' + this.height);

        asyncI++;

        if (asyncI < asyncCount) {

            //go to next loop iteration
            console.log('continue ' + asyncI);
            readImageDimensions();

        } else {

            //exit loop
            console.log('END');
            functionToContinueWith();

        }
    }
}

//call the function
readImageDimensions();
