Title: Prevent processing same image twice that caused image flickr.

In some use cases, Echo.init may be called more than once. Since it doesn't accept any selector to confine the scope of the images yet, I'm adding a data attribute to the image to prevent setting the src attribute more than once. I noticed as least in Chrome, setting the src attribute more than once in short intervals caused the images to flickr.
