Slider images loading before CSS

Hi,

I love your plugin, it’s the best Slider plugin I’ve seen so far. I’m just facing one problem here and it’s on the page loading: I have a slider with 4 images and for some reason when the page loads they all look one below the other displayed as block. Once the body loads, slider works perfectly, so I wonder if there’s a CSS rule to add so I can hide the slider images (except the first one) until the JS and CSS loads completely. I can send you a screenshot if needed!

Thanks a lot!!
