create hash from image contents with PHP?

I currently create a hash from an image name but would rather create a hash based on the contents of an image so I can detect duplicate images. Are their any PHP classes that do this?

My current code is very simple:

$image = "image1.jpg"; 
$filehash = md5_file($image );

As you mention content, you might want to have a look at a perceptual hash, such as phash

The current code you have is actually calculating the md5 of the file contents. What you already have does what you want.
