Styles for drag-and-drop?

[a.cheetham at utoronto.ca]

We're currently implementing the mouse-based drag-and-drop  
functionality in the Lightbox, and it has raised questions about what  
the interface should look like when mousing and clicking, etc.

Questions:

Should the appearance of a thumb change to our 'active' look when  
moused over, or should this only happen when clicked on?

While a thumb is being dragged, should a representation of it stay  
somehow where it was originally? If so, what should it look like?  
(Note: If nothing stays there, the space collapses and all of the  
subsequent images move.)

How should 'previewing' of the target location behave? Should a ghost  
of the thumb be placed in the target location, or should it be a  
vertical bar, like iPhoto, or something else?
