Hi
1/ Do you mean the map in detailed page? You can open file:
Look for this code:
<div class="article-sidebar-box">
<?php if (!empty($latlong)): ?>
{jaosmap locations='{"location":{"0":"<?php echo $this->item->title; ?>"},"latitude":{"0":"<?php echo $latlong[0]; ?>"},"longitude":{"0":"<?php echo $latlong[1]; ?>"},"info":{"0":"<?php echo $this->item->title; ?>"},"icon":{"0":""}}' zoom='12' map_width='396' map_height='396'}{/jaosmap}
<?php endif; ?>
</div>
you can remove code which renders the map and add your own code there:
<div class="article-sidebar-box">
<!-- your code goes here -->
...
</div>
2/ I'm not entirely sure of the price here, how you want to achieve?
