Ok, i have found problem, do this:
<a href="../../images/all/school/02_newspaper/newspaper_01.jpg" rel="prettyPhoto[gallery1]">
<img src="../../images/all/gallery_thumbnails/school/02_newspaper/newspaper-thumb_01.jpg" alt="">
</a>
Wrap your images inside link (a tag), like above. Your current code:
<a href="../../images/all/school/02_newspaper/newspaper_03.jpg" rel="prettyPhoto[gallery1]"></a>
<img src="../../images/all/gallery_thumbnails/school/02_newspaper/newspaper-thumb_03.jpg" alt="">
question is actually - how this is working in other browsers. :)
