Template:Transclude excerpts as random slideshow/doc

A template to make a random slideshow of transcluded excerpts. See Wikipedia_talk:WikiProject_Portals/Design.

Usage
Parameters are the same as for Transclude random excerpt: 

The template accepts any number of page names as unnamed parameters. The slideshow order is selected randomly. Include a namespace where necessary. There are no other positional parameters, but there are some optional named parameters:
 * A list of paragraphs such as ; the default is all paragraphs.
 * A list of file (image) numbers such as ; the default is no images.  Note that images within infoboxes etc. are not available.
 * Arguments to pass to File: such as  to move images to the left; the default is none.
 * Prevent randomisation of the output by setting no (or false).
 * Allow stubs to be included by setting no (or false). The default is to exclude stubs from the slideshow, unless every article is a stub.
 * no – to suppress link to the article at the end of the excerpt. custom text to customize the link text at the end of the excerpt. Default is "Full article...".

Note that this template limits the number of excerpts in the slideshow to 25. This is to prevent transcluding pages from exceeding various technical limitations. If more than 25 page names are provided, a random subset of 25 will be shown. A lower limit may be set using limit if necessary, i.e. to prevent "" errors either in this template or further down the page (example).
