Would greatly appreciate some expert knowhow.

Could somebody please explain how do I get transparent shadows with alpha transparent images to work properly on top of any coloured background (desktop). I get grey shadows...flat grey instead of black and blending into the background.

The alpha transparent images are used for the rainlendar and sysmetrix skins. I have no problems with the skins just shadows. Btw, the backgound to the png images is clear and shadows appear to be working until I apply the skin on the desktop. The skin retains transparency on application but not the drop shadows.

Using PS or PSP.
Thank you in advance.
