[Help Wordpress] Inner shadow

Inner shadow

Hi,

I put the slider in a div, and I want to see a inner shadow inside that div. I used the css box-shadow tag, but it will stick under the slider. The images are over it, I tried putting the div inside the "Slide markup" as you suggested on an other thread. But it still doesn't work.
I tried a custom skin as well, but whatever I do the shadow sticks behind the pictures.

Thank you for your help and your great work.
El.

P.S: Maybe an option for drop/inner shadow could be implemented in the admin area.
