No reason to BOLD lines. It just makes it annoying.

JavaScript does not have the capabilities to do the binary comparison necessary for this nor will it have access to all folders on a client system.

I think you might be mistaken here! HTML 5 has added quite a lot of functionality as far as image processing is concerned. I agree that there would be issues accessing the file on the users system, but if both images could be loaded into the page, JavaScript definitely can do the check to see if the images are the same. Have a read on HTML 5 and its Canvas element.

Yes there are quite a number of unapproved frameworks available. Not all browsers support HTML5 nor all of the capabilities or implement them the same. Solutions should not be given which rely on such capabilities.
