I am running MediaWiki 1.24.1 , PHP 5.5.9-1ubuntu4.7, MySQL 5.5.41-0ubuntu0.14.04.1.
When I click on a image in any template I might use - I now choose Template:Auto images at Wikipedia , for example located at http://en.wikipedia.org/wiki/Template:Auto_images Clicking on the image it is then screened from URL - ...../...../Template:Auto_images#/media/File:example.jpg which shows the original size image in my browser and allows a slideshow-like possibility when there is more than on image on the page.
In my wiki, after creating a page with loaded image, I click on the image and the image is then screened from URL - ..../mediawiki/index.php/File:example.jpg and only by clicking on "Original file" do I get the full image in my browser - URL - ..../mediawiki/images/example.jpg
Two questions: 1) How do I make my wiki behave like the Template:Auto images, and screen "full size" "Original size" image in the browser ? 2) Clicking on the "Original size" link the URL shows ..../mediawiki/images/example.jpg , but the directory /usr/share/mediawiki/images/ is empty ?
