Drag & Drop for Images and Layers: Two things here. First, this is a truly staggering example of what can be done with DHTML. It left me slack-jawed at the possibilities. Second, hats off to Walter Zorn for developing something like this and putting it online. It’s well-coded and — perhaps more importantly — well-documented. This is an all-too-rare example of someone with the willingness to share knowledge and the care and attention to do it well.
