About: Slim uses a scrolling carousel
It is configurable on three levels:
* Slim Piwigo is very thin: most menus, plus comments, plus info on images and just a lighting box to open.
* Slim_XL: Piwigo has grown a bit: it has a search menu, but still just the lighting box and still no comments.
* Slim_XXL: Piwigo recovers all these functions, it has added weight.
Slim is configurable in three colors.
