The following code would produce a more complex slideshow:
Example3.png|'''[[Help:Wikitext|Wikitext]]''' can be used in gallery captions.
Example4.png|Clicking photo takes you to [[Help:Contents]].|link=Help:Contents|linktext=Help:Contents
In this example...
The first item is an image only.
The second item is an image with a caption.
The third item is an image with a caption that includes wikitext
The fourth item is an image that is linked to a wiki page. It also includes a caption, as well as a description of the link.
A slider is an image module that spans the full width of the page and automatically scrolls through up to four images.
Tip: For best results, use images that are exactly 670 x 360px.
