+[[!template id=plugin name=album author="[[Simon_McVittie|smcv]]"]]
+[[!tag type/chrome]]
+
+Available from [[smcv]]'s git repository, in the `album` branch
+([[users/smcv/gallery|users/smcv/gallery]] contains some older
+thoughts about this plugin).
+
+This plugin formats a collection of images into a photo album,
+in the same way as many websites: good examples include the
+PHP application [Gallery](http://gallery.menalto.com/), Flickr,
+and Facebook's Photos "application". I've called it `album`
+to distinguish it from [[contrib/gallery|plugins/contrib/gallery]],
+although `gallery` might well be a better name for this functionality.
+
+The web UI I'm trying to achieve consists of one
+[HTML page of thumbnails](http://www.pseudorandom.co.uk/2008/2008-03-08-panic-cell-gig/)
+as an entry point to the album, where each thumbnail links to
+[a "viewer" HTML page](http://www.pseudorandom.co.uk/2008/2008-03-08-panic-cell-gig/img_0068/)
+with a full size image, next/previous thumbnail links, and
+[[plugins/comments]].
+
+(The Summer of Code [[plugins/contrib/gallery]] plugin does the
+next/previous UI in Javascript using Lightbox, which means that
+individual photos can't be bookmarked in a meaningful way, and
+the best it can do as a fallback for non-Javascript browsers
+is to provide a direct link to the image.)
+
+## Writing the viewers
+
+    \[[!albumimage image=foo.jpg album=myalbum
+        title=...
+        caption=...
+        copyright=...
+        size=...
+        viewertemplate=...
+    ]]
+
+Each viewer contains one `\[[!albumimage]]` directive. This
+sets the `image` filename, the `album` in which this image appears,
+and an optional `caption`, and can override the `size` at which to
+display the image and the `viewertemplate` to use to display the
+image.
+
+It can also have `title`, `copyright` and `date` parameters, which
+are short-cuts for [[ikiwiki/directive/meta]] directives.
+
+The viewer can also have any other content, but typically the
+directive will be the only thing there.
+
+Eventually, there will be a specialized CGI user interface to
+edit all the photos of an album at once, upload a new photo
+(which will attach the photo but also write out a viewer page
+for it), or mark an already-uploaded photo as a member of an
+album (which is done by writing out a viewer page for it).
+
+The `\[[!albumimage]]` directive is replaced by an
+[[ikiwiki/directive/img]], wrapped in some formatting using a
+template (by default `albumviewer.tmpl`). The template can (and
+should) also include "next photo", "previous photo" and
+"up to gallery" links.
+
+The next/previous links are themselves implemented by
+[[inlining|ikiwiki/directive/inline]] the next or previous
+photo, using a special template (by default `albumnext.tmpl`
+or `albumprev.tmpl`), in `archive`/`quick` mode.
+
+## Writing the album
+
+The album contains one `\[[!album]]` directive. It may also
+contain any number of `\[[!albumsection]]` directives, for
+example the demo album linked above could look like:
+
+    \[[!album]]
+    <!-- replaced with one uncategorized photo -->
+
+    ## Gamarra
+
+    \[[!albumsection filter="link(gamarra)"]]
+    <!-- all the Gamarra photos -->
+
+    ## Smokescreen
+
+    \[[!albumsection filter="link(smokescreen)"]]
+    <!-- all the Smokescreen photos -->
+
+    ...
+
+The `\[[!album]]` directive is replaced by an
+[[ikiwiki/directive/inline]] which automatically includes every
+page that has an `\[[!albumimage]]` directive linking it to this
+album, except those that will appear in an `\[[!albumsection]]`.
+
+The `inline` is in `archive`/`quick` mode, but includes some
+extra information about the images, including file size and a
+thumbnail (again, made using [[ikiwiki/directive/img]]). The
+default template is `albumitem.tmpl`, which takes advantage
+of these things.
+
+Each `\[[!albumsection]]` is replaced by a similar inline, which
+selects a subset of the photos in the album.

+[[!tag type/chrome patch]]
+
+Available from [[smcv]]'s git repository, in the `trail` branch. This
+plugin aims to solve [[todo/wikitrails]] in a simpler way.
+
+Joey: what do you think of this plugin? If you like the general approach
+and are likely to include it in ikiwiki, I'll try to modify
+[[plugins/contrib/album]] to be based on it, rather than partially
+reinventing it.
+
+This plugin can benefit from
+[[another_of_my_branches|todo/inline_plugin:_specifying_ordered_page_names]]
+but does not require it.
+
+----
+
+[[!template id=plugin name=trail author="[[Simon_McVittie|smcv]]"]]
+
+It's sometimes useful to have "trails" of pages in a wiki, as a guided
+tour, sequence of chapters etc. In this plugin, a trail is represented
+by a page, and the pages in the trail are indicated by specially marked
+links within that page.
+
+If using the default `page.tmpl`, each page automatically displays the
+trails that it's a member of (if any), with links to the trail and to
+the next and previous members.
+
+The `traillink` [[ikiwiki/directive]] is used to record which pages
+are in a trail, and simultaneously link to them. Alternatively, the
+[[ikiwiki/directive/inline]] directive can be used with `trail=yes`
+to record the inlined pages as part of the trail, in the order in
+which they are inlined.
+
+## Directives
+
+(These will go to the appropriate pages in [[ikiwiki/directive]] if this
+plugin is included in ikiwiki.)
+
+### traillink
+
+The `traillink` directive is supplied by the [[!iki plugins/contrib/trail desc=trail]]
+plugin. This directive appears on the page representing a trail. It acts
+as a visible [[ikiwiki/WikiLink]], but also records the linked page as
+a member of the trail.
+
+Various syntaxes can be used:
+
+    \[[!traillink Badgers]]
+    \[[!traillink How_to_find_mushrooms_using_badgers|badgers]]
+    \[[!traillink badgers text="How to find mushrooms using badgers"]]
+
+### trailoptions
+
+The `trailoptions` directive is supplied by the [[!iki plugins/contrib/trail desc=trail]]
+plugin. This directive appears on the page representing a trail, and
+produces no output.
+
+Currently, the only option supported is `[[!trailoptions circular=yes]]`,
+which adds links between the first and last pages, turning the trail into
+a circle.
