You can use the onerror event in JavaScript to act when an image fails to load:

var img = document.getElementById(myImg);

img.onerror = function () { 

    this.style.display = none;

}

In jQuery (since you asked):

$(#myImg).error(function () { 

    $(this).hide(); 

});

Or for all images:

$(img).error(function () { 

    $(this).hide();

    // or $(this).css({visibility:hidden}); 

});

You should use visibility: hidden instead of .hide() if hiding the images might change the layout. Many sites on the web use a default no image image instead, pointing the src attribute to that image when the specified image location is unavailable.
