lyochum1 You can go to /modules/mod_jaimagehotspot/tmpl/default.php file and change around line 52 :
class="point <?php echo $classpoint.' point'.$i; ?>"
href="javascript:void(0)"
to
class="point <?php echo $classpoint.' point'.$i; ?>"
href="#"
or create template override of the specific module as per procedure outlined here which will help in not loosing modifications with upgrading Joomla version in the future
