The width was already set at 1/6.
This is the shortcode I have inserted:
[clients item_count="12" category="am-1" carousel_auto="yes" pagination="no" width="1/6" el_position="first last"]
The problem is not so much that’s it’s too big, but when I click on the arrow to see the other images in the carousel, it doesn’t bring me to the next image, it goes to the 6th one. Either the carousel is too fast, or the images are too big….
