I mean a button with a link to another address or even a facebook share button.
Overall I was wondering if is possible to implement some script on the page where the large image is displayed.
E.g.:
<script>function fbs_click() {u=location.href;t=document.title;window.open('
www.facebook.com/sharer.php?u='+encodeURIComponent(u)+'&t='+encodeURIComponent(t),'sharer','toolbar=0,status=0,width=626,height=436');return false;}</script><a rel="nofollow" href="
www.facebook.com/share.php?u=<;url>" onclick="return fbs_click()" target="_blank">Share on Facebook</a>
thanks!
