problem solved.
for those who need the same thing they can do it by removing this line:
<th align="center" valign="middle" class="navmenu" width="48">
<a href="<{$slideshow_tgt}>" title="<{$slideshow_title}>"><img src="images/slideshow.gif" width="16" height="16" border="0" align="middle" alt="<{$slideshow_title}>"/></a>
</th>
from xcgal/templates/xcgal_display.html
and all is okay after that.
Case closed!
