A Cross-browser JavaScript DHTML Library which adds Drag Drop functionality to layers and to any desired image, even those integrated into the text Drag & Drop Image flow. The idea behind wz_dragdrop.js was not merely to drag around some layers or images on a page in IE only, but also to be a cross-browser clientside API for interactive webpages and webbased applications.
