Do you really want all those images in one long row? unsure.gif

Because of the different resolutions you can't rely on pixel units (and it's safest to avoid the "position" property in general). Some alternatives are shown here: https://www.w3.org/Style/Examples/007/center.html

Maybe some of them are positioned outside the viewport? That may happen when using large positioning offset values.
