Hello.
I know this question already often appeared in forums, but I can't find any good answer (for my knowledge in coding ... and in english. I'm french).

So, my template has this :
<script type="text/javascript" src="/mysite/media/system/js/mootools.js"></script>
that is used for a slideshow in the header.

And it is impossible to make the header's slideshow and Simple Image Gallery working in the same page.

A solution ?
