Well, here's another way.
In your includes/page_header.php file,
find :
"url_home" => $site_sess->url(ROOT_PATH."index.php"),
add right below :
"url_caminator" => "http://www.caminator.com",
Then, find :
"lang_sub_categories" => $lang['sub_categories'],
add below :
"lang_caminator_back" => $lang['caminator_back'],
Then, in your lang/english/main.php file,
add above the '?>' tag :
$lang['caminator_back'] = "BACK TO CAMINATOR.COM";
Then, in your templates/<your_template>/details.html file,
replace :
<a href="http://www.caminator.com">BACK TO CAMINATOR.COM</a>
with :
<a href="{url_caminator}">{lang_caminator_back}</a>
These should do it.
Note: If you plan to redirect your loggedin users into another location (so, elsewhere from your gallery), their account will
still be active. Meaning, I personally would consider to log out from their account before moving into another location. You should leave an additional note close to your link or something.
