How can I asynchronously load external images using jQuery?

Asynchronous Image Loading with jQuery

Question: Is it possible to asynchronously load external images using jQuery? If so, how?

Response:

Yes, it is possible to asynchronously load images using jQuery. Here are two methods you can use:

Method 1: Using an XHR Request

$.ajax({
    url: "http://somedomain.com/image.jpg",
    timeout: 5000,
    success: function() {
        // Handle success
    },
    error: function(r, x) {
        // Handle error
    }
});
Copy after login

However, this method may not always return an error for unavailable images.

Method 2: Using the load Method

var img = $('<img />').attr('src', 'http://somedomain.com/image.jpg')
    .on('load', function() {
        if (!this.complete || typeof this.naturalWidth == "undefined" || this.naturalWidth == 0) {
            alert('Broken image!');
        } else {
            $("#something").append(img);
        }
    });
Copy after login

This method allows you to handle 404 errors by checking if the image is broken or not.
