Slider on multi-image CMS collection random load

Hello everyone,

Here’s my read-only link.

See that slider ? He is based on a CMS image collection in display none : sometimes there is 4 images in, sometimes there is 8, or 6, etc… It’s random.

And what i don’t understand is :

  • In some pages, it works, slider contain only images, like there.
  • But in the most of them, it doesn’t work, like here.
    EDIT : I just realize by cliking on my link that it’s totally random too… So it’s totally random :confused:

Maybe it’s a size image problem ? But i’m not sure.

Big thanks by advance <3
