This site Containing smoothing effect (smooth) links within the page. And Gallery (ad-gallery).
Somehow these two elements collide each other and dont work together.
When leveling works first gallery images disappear.
You can take a look and tell me why?
To turn off smoothing (smooth) just remove the following line from index.html
<script type="text/javascript" src="js/smooth.scroll.js"> </ script>

Sorry but I can not upload the site here he increases (it weighs 3 MB) so the download address is:

Thank you in advance ...
