This is because you did it backwards. You built the page around the enhancement. What you're supposed to do is build the page without Javascript, then apply Javascript as an enhancement. That way, if Javascript is disabled, it still works. No worries, it's pretty common . . . .

What I'd suggest at this point is find the elements that offend thee (Guessing the spans and paths?) and set their display to none:

.dg-image-gallery-large-image-path { display: none; }

Then use the Javascript to reveal them, if you need to.

<script type="text/javascript">
var gallery = new DG.ImageGallery({
el : 'dg-image-gallery',
autoplay : {
pause : 2
}
});
$('.dg-image-gallery-large-image-path').css('display','block');
</script>

Something along those lines . . .

Thanks but did not work, however one gave me a solution,
this in the header:

 <script type="text/javascript">window.addEvent('domready', function() {
 $$('html').set('class', 'jsOn');
});
</script>

An alternative content instead of <noscript>:
<p class="alternative">no javascript content/p>

this in the .css file:
.dg-image-gallery {
display: none;
}
.jsOn .dg-image-gallery {
display: block;}
.jsOn .alternative {display:none; }

Thanks,
