Hi,
Please open file root_folder/modules/mod_jaimagehotspot/tmpl/default.php, look for this code and add target attribute there :
<a style="top:<?php echo $des->offsety; ?>%;left:<?php echo $des->offsetx; ?>%"
class="point <?php echo $classpoint.' point'.$i; ?>"
href="<?php echo trim($des->link) ? $des->link : 'javascript:void(0)' ?>"
id="<?php echo 'ja-marker-'.$des->imgid; ?>"
data-toggle="popover"
data-placement="top"
title="<?php echo $des->title; ?>"
data-content="<?php echo htmlspecialchars($des->details, ENT_COMPAT, 'UTF-8'); ?>" data-html="true">
<span class="hidden">Point</span>
</a>
<?php else: ?>
<a style="top:<?php echo $des->offsety; ?>%;left:<?php echo $des->offsetx; ?>%"
class="point <?php echo $classpoint.' point'.$i; ?>"
href="<?php echo trim($des->link) ? $des->link : 'javascript:void(0)' ?>"
id="<?php echo 'ja-marker-'.$des->imgid; ?>"
title="">
<span class="hidden">Point</span>
</a>
