Firefox "onerror" would not fire even when image is not valid

Question

Hi folks, I have a onerror handler on the image tag to handle switching when the remote image is not found.

the problem is that for certain broken remote images, it does not work.

<img onerror="this.src='/images/pic_not_found.png'" src="http://a3.twimg.com/profile_images/522455109/calvin-and-hobbessm_normal.jpg"&gt;

Image below: 1) when remote image found, 2) remote image not found (onerror not triggered) , 3) remote image not found (onerror triggered)

Answer 1

It is not a broken link ...

The twimg.com actually returns an image with the name of the url you requested.. so an image is returned ..

just clink your link to the image. It is not text what you are seeing .. it is an image..

Update

Here is some code that works in all browsers... does some basic feature detection ..

It uses both onload and onerror, but requires a function defined in javascript to handle the situation ..
