@team2step. Well, it is obvious that the images can’t be found. However, the files should be located at the path that is specified in the img src. As the webmaster of your site, you need to figure out why that is happening. If the files are located in media/mod_easyfolderlisting/icons, then they should be able to access the files such as http://1uc.org/media/mod_easyfolderlisting/icons/page_white_acrobat.png.
Most likely, your htaccess file is blocking direct access to files in the media folder. If you check your Apache error logs, it should list any blocking errors to files. I really believe it might be the htaccess. I even tried to access a system image: http://www.1uc.org/media/system/images/notice-note.png, and it didn’t show. If you try to access the same image on my website it will show: https://www.valorapps.com/media/system/images/notice-note.png
