Transparent background on slides.

i've tried many things,
but i'm not able to make the background of the slide transparent.
if changing the wrapper, is see the site background
i just want to see the overlapped image.
look at my site, and you will understand. (the left uppercorner of each slide should be transparent, and show the underlaying slide)

My images are already transparent. I need css code to make the ba[quote][/quote]ckground of the images transparent now it is solid black... Or the transparency goes trough the underl
aying picture
If you look at my site you can observe that the upperleft corner is black.
My question is then. ... Why and wich layer do I see. Is it the same layer as the website background or is it only the place holder of the image. If it is the background from the site, the transparency is ok and the issue is with the java not sliding over the picture,but cropping the underlaying pictures

Please help

It appears the background for the sliders is the background for the body. I made the body transparent here with firebug by removing the color

#wrapper {
margin-top: 20px;
padding: 0 20px;
position: relative;
}
style.css (line 208

but it makes the whole body transparent
