+===== Internal image with slideshow grouping =====
+**Why?**
+  * To decide which image will have lightbox slideshow
+  * Group together images into slideshow on one page as you like
+**How?**
+  * Apply new internal image hash parameter ''ss'' [:slide-show:]
+  * Grouping is done by the value of ''ss'' parametter which is number and it is mandatory
+**E.g.**
+<code>
+{{imagefile1.jpg#ss=1?640x480}} <- Slideshow group #1
+{{imagefile2.jpg#ss=1?640x480}} <- Slideshow group #1
+{{imagefile3.jpg#ss=2?640x480}} <- Slideshow group #2
+{{imagefile4.jpg#ss=2?640x480}} <- Slideshow group #2
+{{imagefile5.jpg?640x480}} <- Image without slideshow! :)
+</code>
+:!: Notice that all hash parameters started by ''#'' sign are right after the filename and before the regular image link parameters, before the ''?'' symbol!
+**How to implement this adjustment?**
+  * Find file ''inc/parser/xhtml.php''
+  * Find ''function internalmedia()''
+  * Find this line:
+<file php>
+$link['url'] = ml($src, array('id' => $ID, 'cache' => $cache, 'rev'=>$this->_getLastMediaRevisionAt($src)), ($linking == 'direct'));
+</file>
+  * Insert 8 new lines before line above:
+<file php>
+// activate lightbox slideshow group by #ss=1
+if (!is_null(plugin_load('syntax', 'gallery'))) {
+    $match = array();
+    if (preg_match('/(?:^|(?<=&))ss=(\d+)(?:(?=&)|$)/', $hash, $match)) {
+        $linking = 'direct';
+        $link['rel'] = 'lightbox[gal-'.substr(md5($ID.'#ss='.$match[1]),4).']';
+    }
+}
