&gt; Dear Contexters!<br>
&gt; In the last few days I could read a few posts about<br>
&gt; &quot;animations&quot; in a resulting PDF document. Some<br>
&gt; statements mentioned java script as possible means<br>
&gt; to create an animation.<br>
&gt; Is it possible to do the following (which is rather<br>
&gt; simple using html and javascript)?<br>
&gt;<br>
&gt;   -- Have a bunch of thumbnail pictures<br>
&gt;   -- When you click on a thumbnail you see a<br>
&gt;      larger version of the same picture<br>
&gt;   -- With the next mouseclick the picture<br>
&gt;      vanishes (you see the gallery of thumbnails again)<br>
&gt;<br>
&gt; if yes, how?<br>
&gt; Any hints are welcome.<br>
<br>
</div></div>Not perfect (it’s not possible to close the big pictures) but it should give you a first impression:<br>
