Detect mime type of an image via Javascript

Question

i am detecting images on my webpage with javascript document.images function which returns an rray of images. Is there any way to get the mime type of the image from this si

Answer 1

I don't think this is possible, apart from requesting the image again in jQuery and trying to use a MIME type check on the data. (You might be able to send a HEAD request and get whatever Content-type was returned)
