Hi,

I have an image with a white background and a drop shadow.

The problem is that the image is flat and I would like it to be
transparent.

The real problem is in the flat drop shadow where it is desired to
have a gradient transparency from 100% to 0 (from outside to inside).

Whats the best way to do it?

Double click the background layer to make it a normal layer. Go to the
Channels palette and click on the RGB icon while holding the Ctrl-key
(Cmd-key on a Mac). That will load a selection based on luminosity.
Choose the rectangular selection tool and while holding down the
Alt-key, select the image itself. This will subtract the image from the
selection, so you only have the shadow and he white background selected
by luminosity. Hit the delete key to delete the selection.
