Set a background in the slideshowck

Hello Cédric,

Another small question for my site cristal-paris.com (je te le fais en anglais pour être plus global, better for you )

I would like to do the following with slideshowck
- set a background, which is actually the photo of a frame (un cadre de tableau)
- place the imported image inside this frame with specific dimensions
- the imported image should fit whatever its dimension to the width and height of this inside block

Currently in the site the background is located on the container of the slideshow and I modified the module CSS to fit inside the frame but its not clean and when the image doesn't fit exactly the dimensions it stays on the left and doesn't get centered.






I tried to check in the module CSS but cannot figure out where to place it in the cascade of containers ?

I guess to fit the inside container is a question of "max-width : 100%" but again
=> where to place it in the CSS ?



Thanks for your help

Christophe
