The first fourth picture

It displays perfectly in chrome, so that problem is caused only by browser, probably can not render cross-fade as it should, so maybe changing animation type can be solution if the fact that it it not displayed well in some bad browser bothers you so much .

Hello,

the problem is the same in all browsers.

But I eventually not adequately explain the problem.
With each page refresh, the last image that starts.

Now I added the same image in the fifth position as the first and I deleted the:

#slider img{
display:none;
}

in the template.css, I think I'll leave it like that.

Thank you
