Features

 * Also includes images from infoboxes and such
 * Intuitive user interface
 * Small footprint (less than 1000 lines of JavaScript, small style sheet, few external images and dependencies)
 * Integrates Wikimedia Commons (if the article contains a link to a category on commons, the Slideshow will include pictures from it)
 * Features a cookie-based mechanism for storing personal preferences
 * Ability to be internationalized (all i18n-relevant strings are stored at a central site, one can easily override default markup and strings via cookies)

How to install

 * 1) Open your common.js file (for example )
 * 2) Insert the following line of code:
 * 3) Clear your browsers' cache
 * 4) Thats it! If you encounter any problems, feel free to contact me via [marian.beermann@yahoo.de]

How to use
You're only able to invoke a slideshow on articles which actually contain images. The slideshow is invoked via the "Slideshow" link after the "Read" tab.

Keyboard shortcuts
I implemented a few shortcuts for better usability, supporting both navigation via the arrow keys or the well-known WASD keys

Settings
Click on the "Slideshow settings" link to the right side of the "My Preferences" link in your personal toolbar to open the settings. If you click the "Save" button everything will be stored as cookies with an expiration date of 10 years ahead - delete the cookies to reset everything back to the default settings. Please note, that changing the commons settings will only take effect if the slideshow hasn't been invoked yet or if the page is reloaded, as the slideshow is actually not deleted when the "Close"-Button is pressed (for perfomance reasons).

If you want to override settings that are not configurable by default, you can just set a cookie with the name of the variable prepended by "Slideshow." to basically any value that makes sense. E.g. the cookie for the variable i18n.Slideshow would be Slideshow.i18n.Slideshow.

Mobile vs. standard mode
The standard mode is designed for todays big screens which much space. In this mode captions and a bar with thumbnails are shown, the controls are always visible etc. whereas the mobile mode is for smartphones and tablets, which are usually operated via their touchscreens. In the mobile mode resizing support is very limited (and disabled by default) to save as much CPU time as possible in order to save as much energy as possible. Images are also scaled server side to save the often limited bandwith; to save screen space the controls will become only visible when hovered (^= touched), but they will also remain active when invisible, which should be the most intuitive solution for this. There are no captions, either.

Slideshow Challenge: General Considerations

 * If I'm a Wikipedia reader, how do I activate a slideshow?
 * The slideshow is activated via the Slideshow button near the read button (views toolbar - In my opinion a slideshow is just another view of an article)


 * How will captions be surfaced?
 * If an image has a caption, it will be shown under the image in the slideshow


 * How will users interact with the slideshow on a tablet or a smartphone?
 * On screens smaller than 960x640 pixels or with mobile browsers the mobile mode is automatically activated. This incorporates smaller navigation and better usage of the limited screen space.


 * How to deal with different screen resolutions?
 * On the fly resizing is fully supported


 * How do I get access to other image-related metadata, e.g. licensing information?
 * A click on the caption jumps to the image in the article, a click on the image opens the respective File: page in a new window/tab.


 * If a Wikipedia article links to related images on Wikimedia Commons (e.g. through Template:Commons or Template:Commons category), how can those be surfaced in the slideshow?
 * Those images will be displayed as well, with the only difference that a click on the caption opens a new tab/window with the category containing the image

Checklist

 * Did your code run without errors under ? (JS only)
 * Did your code break any of the unit tests? See Manual:PHP unit testing and Manual:JavaScript unit testing As far as I can tell: no
 * Have you tested all exit points from your code? Yes
 * Did you use tabs instead of spaces to indent? Yes
 * If you've created a new function, did you document the function parameters and what it returns using PHPDoc? (JS only)
 * Whitespace trailing at the end of lines is annoying, don't do that (but don't fix whitespace at the end of lines you didn't modify in the same commit, just make sure whatever you touched is good, see next point:) No trailing whitespaces as far as I can see
 * Does this commit contain any whitespace-only changes? They should be isolated to their own separate coding style-only commit. (Not commiting anything ;))
 * Have you created any identifiers that didn't use camelCase (ie. underscores)? No
 * Is every exception tested? I do not use any
 * If you have multiple return points, are they tested? Yes
 * Does each message you've created exist in MessagesEn.php and listed in maintenance/languages/messages.inc? (JS only)
 * Is each use of,  , etc. checked for errors or problems?
 * Did you use  or   flags for   to ensure Windows compatibility?
 * Have you used the proper output functions?   should almost never be used.
 * Have you used the proper termination functions?   should almost never be used.
 * Where appropriate, have you used the MediaWiki wrapper functions instead of their PHP equivalents?
 * instead of  to get boolean params
 * If you add a new test to parserTests.txt did you give it a new name?
 * Have you run ?

JavaScript / CSS

 * Tested in an actual browser? Yes
 * Compatible with IE 6.0+, FF 2.0+, Safari 3.0+, Opera 9.0+, Chrome? IE 9, FF7 (I guess older versions work too), Opera 9, Chrome, Safari
 * (JavaScript) Does it validate (or did you at least run it through) JSHint ? Yes
 * (JavaScript) Are there any implied globals other than  or  ? There should not be, (not   either) None. Everything is handled inside an anonymous function
 * Is it DRY? I would say yes
