 * Hi,
 * The thumbnails in my Slideshow Gallery won’t appear. They are replaced with a
   broken image icon. The strange thing is, it happens for random photos. Whats 
   more… when I right-click on a broken-image-icon, i can get url for the image.
   It turns out that those URLs are **correct**!
 * I’ve done all updates: current plugin, current timthumb, current wordpress.
 * BTW: what does it mean? (its a fix for htaccess, I’ve found on some blog)
 *     ```
       <IfModule mod_security.c>
       SecFilterEngine Off
       SecFilterScanPOST Off
       </IfModule>
       ```
