-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 provides the [[ikiwiki/directive/album]] [[ikiwiki/directive]],
+which turns a page into a photo album or image gallery, containing all
+images attached to the album or its subpages. It also provides the
+[[ikiwiki/directive/albumsection]] and [[ikiwiki/directive/albumimage]]
+directives.
-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".
+This plugin automatically enables the [[filecheck]], [[img]], [[inline]],
+[[trail]] and [[transient]] plugins. The [[meta]] plugin is also
+recommended.
-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.)
-
-album directive
-
-Each page containing an `album` directive is treated as a photo album.
-
-Every image attached to an album or its subpages is considered to be part of
-the album. A "viewer" page, with the wiki's default page extension, will be
-generated to display the image, if there isn't already a page of the same
-name as the image: for instance, if `debconf` is an album and
-`debconf/tuesday/p100.jpg` exists, then `debconf/tuesday/p100.mdwn` might
-be created.
+## Changing the templates
-There's currently a hard-coded list of extensions that are treated as images:
-`png`, `gif`, `jpg`, `jpeg` or `mov` files. More image and video types could
-be added in future. Videos aren't currently handled very well;
-ideally, something like totem-video-thumbnailer would be used.
+When a viewer page is generated or inlined into an album, the template can
+contain these extra variables:
-The `album` directive also produces an [[ikiwiki/directive/inline]] which
-automatically includes all the viewers for this album, except those that
-will appear in an albumsection (if every image
-is in a section, then the `album` directive won't have any visible effect).
+* `` - page name of the album
+* `` - relative URL to the album
+* `` - title of the album, usually taken from
+ a [[ikiwiki/directive/meta]] directive
+* `` - caption for the image
+* `` - a small [[ikiwiki/directive/img]] for the image
+* `` - width of the full-size image in pixels
+* `` - height of the full-size image in pixels
+* `` - size of the image, e.g. `1.2 MiB`
+* `` - format of the image, typically `JPEG`
-The `inline` is in `archive` and `quick` mode, but can include some
-extra information about the images, including file size and a thumbnail made
-using [[ikiwiki/directive/img]]). The default template is `albumitem.tmpl`,
-which takes advantage of these things.
+The template for the viewer page can also contain:
-albumsection directive
+* `` - a large [[ikiwiki/directive/img]] to display the image
+* `` - a link to the previous viewer, typically with a
+ thumbnail
+* `` - a link to the next viewer, typically with a
+ thumbnail
-The `albumsection` directive is used to split an album into sections. It can
-only appear on a page that also has the album directive.
+## Including album entries elsewhere
-The `filter` parameter is a [[ikiwiki/PageSpec]] against which viewer pages
-are matched. The `albumsection` directive displays all the images that match
-the filter, and the `album` directive displays any leftover images, like
-this:
+To display images from elsewhere in the wiki with the same appearance as
+an [[ikiwiki/directive/album]] or [[ikiwiki/directive/albumsection]],
+you can use an [[ikiwiki/directive/inline]] with the `albumitem`
+template:
- # Holiday photos
+ \[[!inline pages="..." sort="-age" template="albumitem"]]
- \[[!album]]
-
+----
- ## People
+[[!template id=gitbranch branch=smcv/album3 author="[[Simon_McVittie|smcv]]"]]
- \[[!albumsection filter="tagged(people)"]]

-albumimage directive
+## Manual installation
-Each viewer page produced by the album directive
-contains an `albumimage` directive, which is replaced by an
-[[ikiwiki/directive/img]], wrapped in some formatting using a
-template (by default it's `albumviewer.tmpl`). That template can also include
-links to the next photo, the previous photo and the album it's in; the default
-template has all of these.
+If you don't want to use a branch of ikiwiki, manual installation requires
+these files (use the "raw" link in gitweb to download), in addition to the
+ones needed by [[trail]]:
-The next/previous links are themselves implemented by evaluating a template,
-either `albumnext.tmpl` or `albumprev.tmpl` by default.
+* [album.pm](http://git.pseudorandom.co.uk/smcv/ikiwiki.git/blob/album3:/IkiWiki/Plugin/album.pm)

-The directive can also have parameters:
+## Demo
-* `title`, `copyright` and `date` are short-cuts for the corresponding
- [[ikiwiki/directive/meta]] directives
+* [HTML page of thumbnails](http://ikialbum.hosted.pseudorandom.co.uk/album/)
+ as an entry point to the album
+* Each thumbnail links to
+ [a "viewer" HTML page](http://ikialbum.hosted.pseudorandom.co.uk/album/img_0120/)
+ with a full size image, optional next/previous thumbnail links, and
+ optional [[plugins/comments]]
-* `caption` sets a caption which is displayed in the album and viewer
- pages
+## Bugs
-The viewer page can also have other contents before or after the actual
-image viewer.
+* There's currently a hard-coded list of extensions that are treated as
+ images: `png`, `gif`, `jpg`, `jpeg` or `mov` files. More image and video
+ types could be added in future.
-## Bugs
+* Videos aren't currently handled very well; ideally, something like
+ totem-video-thumbnailer would be used.
* The plugin doesn't do anything special to handle albums that are subpages
of each other. If, say, `debconf` and `debconf/monday` are both albums,
then `debconf/monday/p100.jpg` will currently be assigned to one or the
- other, arbitrarily.

* The plugin doesn't do anything special to handle photos with similar names.
If you have `p100.jpg` and `p100.png`, one will get a viewer page called

* If there's no `albumimage` in a viewer page, one should probably be appended

-
-* The documentation should mention all the template variables and
- all the parameters.

-* The generated viewer page should include most or all of the possible

* The generated viewer page should extract as much metadata as possible from
