I don't particularly like Facebook's cover photo feature, so I didn't particularly like it when JomSocial followed suit. Here's how to disable JomSocial's cover photo feature altogether.
Backup Your Site
Just in case. The Joomla extension Akeeba Backup does a great job.
Modify the Following JomSocial Template Files
Frontpage cover photo - root/components/com_community/templates/default/frontpage.guests.php
Remove the code:
<div class="row-fluid hero-area">
...
</div>
Profile cover photo - root/components/com_community/templates/default/modules/profile/userinfo.php
Remove the code:
<div class="js-focus-cover">
...
</div>
Group cover photo - root/components/com_community/templates/default/groups.viewgroup.php
Remove the code:
<div class="js-focus-cover">
...
</div>
Event cover photo - root/components/com_community/templates/default/events.viewevent.php
Remove the code:
<div class="js-focus-cover">
...
</div>
Copy the Modified Files to JomSocial Template Overrides
Copy the files you modified to this location:
root/templates/current_template/html/com_community
This is the template override feature that allows you to keep your modifications across JomSocial package upgrades.
