ImagGuard Plugin didn't work

Hi, My website is funmozar.com

Recently I activated imaguard plugin. All of the plugin works well, but only imaguard plugin does not work. Currently it is activated, nut no changes shown in any image URL. Please check this image link:

Its not redirected to post page or other pages.

So, what are the problems?

I see that there are two .htaccess files. One is .htaccess and other files name is .htaccess-phpup-1400169351
In .htaccess-phpup-1400169351 file, I see this extra code:

#Use PHP 5.4
AddType application/x-httpd-php54 .php
<IfModule mod_suphp.c>
suPHP_ConfigPath /opt/php54/lib/php.ini
</IfModule>
