Parallax kicks out some images after iniciation

[mambomario]

Hi, check out mojastaramama.sk/devtest for demo.
not only parallax gets badly positioned on Chrome and Firefox, it also kicks out some images after iniciation. I did follow all the instruction, my divs have postion relative.

It doesnt repeat on reload, I supposed could be issue of browser uploading image
I spent endless hours figuring out what it is, please help.
thank you
Mario

Try position: absolute instead. Does that work?
