Check for empty image

I have a folder full of .jpg images. With a PHP script I'm reading the list of images in the folder and I'm displaying them on the browser.

The problem is that some of the images exist, but something it's wrong with them. They are few Kb but they can't be displayed (on the browser I see like a broken image), of course if I download these images in local I can't see them.

I tried to google but all I found was how to recognize a broken link or an empty img tag, how can I check if the image is displayable? I also tried the onError event but it isn't fired.

IMO, you’d be better off checking this on the server, using PHP. PHP has several functions to load images, such as imagecreatefromjpeg and imagecreatefrompng. Both these functions will return FALSE if there’s an error loading the image. Getting FALSE will tell you that it’s not a valid image.
