Question com_kunena/template/default/images/icons/online.gif & offline.gif & email.png

I do not know where used " online.gif "," offline.gif "and" email.png "but I see that these files are registered in kunena.forum-min.css

online.gif:
#Kunena span.kpost-online-status-yes{display:inline-block;background:url("../images/icons/online.gif") no-repeat;height:15px;width:74px;vertical-align:text-top;}
#Kunena li.kpost-online-status-top-yes{display:block;float:left;padding-right:5px;background:url("../images/icons/online.gif") no-repeat;height:15px;width:74px;}
#Kunena div#kprofile-stats ul li span.konline-status-yes{display:block;background:url("../images/icons/online.gif") no-repeat;height:16px;width:70px;color:#fff;}

Why this code? Why in the distribution are no pictures?
If the code once it is possible to remove it?

I just want to know where the developers make a mistake? With that in com_kunena_v1.6.0_b3620_2010-10-03.zip no pictures or is that in kunena.forum-min.css have an extra code?

Did you get any error message when you tried to install Kunena?

NO

Have you tried to re-install Kunena?

yes

Where are these files "online.gif", "offline.gif" and "email.png" used in K 1.6? Can you show me, please?

See kunena.forum-min.css, I do not know why they're spelled ...

Thanks for the new, nice forum kunena, I'll update the main site

Well the picture that you posted should show us the files in the downloaded ZIP file right?
But this is not the official archive cause this would have another structure.
