Hi.
The module is fully compatible with joomla 3.6.2.
For the link on the image you can try this.
edit the file :
/modules/mod_jaimagehotspot/mod_jaimagehotspot.xml
add this code
<field
type="text"
default="#"
name="imglink"
label="JAI_IMG_LINK"
description="JAI_IMG_LINK_DESC" />
under the code around line 113-126.
<field
name="showchoicelocaltion"
type="list"
default="top-left"
label="JAI_POSITION_OFFICE"
description="JAI_POSITION_OFFICE_DESC">
<option value="top-left">JAI_POSITION_TOP_LEFT</option>
<option value="top-right">JAI_POSITION_TOP_RIGHT</option>
<option value="bottom-left">JAI_POSITION_BOTTOM_LEFT</option>
<option value="bottom-right">JAI_POSITION_BOTTOM_RIGHT</option>
<option value="middle-left">JAI_POSITION_MIDDLE_LEFT</option>
<option value="middle-right">JAI_POSITION_MIDDLE_RIGHT</option>
</field>
and edit the file.
/modules/mod_jaimagehotspot/tmpl/default.php
edit the code :
<img src="<?php echo $imgpath;?>" alt=""/>
To:
<a target="_blank" href="<?php echo $params->get( 'imglink', '#' );?>"><img src="<?php echo $imgpath;?>" alt=""/></a>
You can place it in any position of your template like you want.
Regards.
