Solution 2

function urlExists(testUrl) {
 var http = jQuery.ajax({
    type:"HEAD",
    url: testUrl,
    async: false
  })
  return http.status;
      // this will return 200 on success, and 0 or negative value on error
}

Then use

if(urlExists('urlToImgOrAnything') == 200) {
    // success
}
else {
    // error
}

Solution 1

Try

JavaScript

function testImage(URL) {
    var tester=new Image();
    tester.onLoad=isGood;
    tester.onError=isBad;
    tester.src=URL;
}

function isGood() {
    alert('That image exists!');
}

function isBad() {
    alert('That image does no exist!');
}
