Inline Data - empty div(?) shown

[horstoeko]

With the following markup I get an empty div(?) shown at first by clicking the link:

<a href="#pics" data-rel="lightbox" data-lightbox-type="inline" data-lightbox-gallery="gal1">Load Article</a> 
<div id="pics" style="display:none;">
    <a href="/pic/img_0018.jpg" data-lightbox-gallery="gal1" title="img_0018.jpg, 30.11.-0001, 00:00">
        <img src="/pic/img_0018_thumb.jpg" id="pic1" alt="img_0018.jpg, 30.11.-0001, 00:00" data-textmgr="yes" />
    </a>
    <a href="/pic/img_0020.jpg" data-lightbox-gallery="gal1" title="img_0020.jpg, 30.11.-0001, 00:00">
        <img src="/pic/img_0020_thumb.jpg" id="pic2" alt="img_0020.jpg, 30.11.-0001, 00:00" data-textmgr="yes" />
    </a>
</div>
