4 This plugin provides the [[ikiwiki/directive/album]] [[ikiwiki/directive]],
5 which turns a page into a photo album or image gallery, containing all
6 images attached to the album or its subpages. It also provides the
7 [[ikiwiki/directive/albumsection]] and [[ikiwiki/directive/albumimage]]
10 This plugin automatically enables the [[filecheck]], [[img]], [[inline]],
11 [[trail]] and [[transient]] plugins. The [[meta]] plugin is also
14 ## Changing the templates
16 When a viewer page is generated or inlined into an album, the template can
17 contain these extra variables:
19 * `<TMPL_VAR ALBUM>` - page name of the album
20 * `<TMPL_VAR ALBUMURL>` - relative URL to the album
21 * `<TMPL_VAR ALBUMTITLE>` - title of the album, usually taken from
22 a [[ikiwiki/directive/meta]] directive
23 * `<TMPL_VAR CAPTION>` - caption for the image
24 * `<TMPL_VAR THUMBNAIL>` - a small [[ikiwiki/directive/img]] for the image
25 * `<TMPL_VAR IMAGEWIDTH>` - width of the full-size image in pixels
26 * `<TMPL_VAR IMAGEHEIGHT>` - height of the full-size image in pixels
27 * `<TMPL_VAR IMAGEFILESIZE>` - size of the image, e.g. `1.2 MiB`
28 * `<TMPL_VAR IMAGEFORMAT>` - format of the image, typically `JPEG`
30 The template for the viewer page can also contain:
32 * `<TMPL_VAR IMG>` - a large [[ikiwiki/directive/img]] to display the image
33 * `<TMPL_VAR PREV>` - a link to the previous viewer, typically with a
35 * `<TMPL_VAR NEXT>` - a link to the next viewer, typically with a
38 ## Including album entries elsewhere
40 To display images from elsewhere in the wiki with the same appearance as
41 an [[ikiwiki/directive/album]] or [[ikiwiki/directive/albumsection]],
42 you can use an [[ikiwiki/directive/inline]] with the `albumitem`
45 \[[!inline pages="..." sort="-age" template="albumitem"]]
49 [[!template id=gitbranch branch=smcv/album3 author="[[Simon_McVittie|smcv]]"]]
51 Available from [[smcv]]'s git repository, in the `album3` branch.
52 I've called it `album` to distinguish it from
53 [[contrib/gallery|plugins/contrib/gallery]], although `gallery` might well be
54 a better name for this functionality.
56 (The Summer of Code [[plugins/contrib/gallery]] plugin does the
57 next/previous UI in Javascript using Lightbox, which means that
58 individual photos can't be bookmarked in a meaningful way, and
59 the best it can do as a fallback for non-Javascript browsers
60 is to provide a direct link to the image.)
62 Updated, November 2011: rebased onto [[trail]] v3, CSS adjusted.
64 ## Manual installation
66 If you don't want to use a branch of ikiwiki, manual installation requires
67 these files (use the "raw" link in gitweb to download), in addition to the
68 ones needed by [[trail]]:
70 * [album.pm](http://git.pseudorandom.co.uk/smcv/ikiwiki.git/blob/album3:/IkiWiki/Plugin/album.pm)
71 in an `IkiWiki/Plugin` subdirectory of your configured `plugindir`
72 * [albumviewer.tmpl](http://git.pseudorandom.co.uk/smcv/ikiwiki.git/blob/album3:/templates/albumviewer.tmpl),
73 [albumitem.tmpl](http://git.pseudorandom.co.uk/smcv/ikiwiki.git/blob/album3:/templates/albumitem.tmpl),
74 [albumnext.tmpl](http://git.pseudorandom.co.uk/smcv/ikiwiki.git/blob/album3:/templates/albumnext.tmpl) and
75 [albumprev.tmpl](http://git.pseudorandom.co.uk/smcv/ikiwiki.git/blob/album3:/templates/albumprev.tmpl),
76 in your configured `templatedir`, or a `templates` subdirectory of your wiki repository
77 * the album-related bits from the end of the
78 [stylesheet](http://git.pseudorandom.co.uk/smcv/ikiwiki.git/blob/album3:/doc/style.css)
79 (put them in your local.css)
83 * [HTML page of thumbnails](http://ikialbum.hosted.pseudorandom.co.uk/album/)
84 as an entry point to the album
85 * Each thumbnail links to
86 [a "viewer" HTML page](http://ikialbum.hosted.pseudorandom.co.uk/album/img_0120/)
87 with a full size image, optional next/previous thumbnail links, and
88 optional [[plugins/comments]]
92 * There's currently a hard-coded list of extensions that are treated as
93 images: `png`, `gif`, `jpg`, `jpeg` or `mov` files. More image and video
94 types could be added in future.
96 * Videos aren't currently handled very well; ideally, something like
97 totem-video-thumbnailer would be used.
99 * The plugin doesn't do anything special to handle albums that are subpages
100 of each other. If, say, `debconf` and `debconf/monday` are both albums,
101 then `debconf/monday/p100.jpg` will currently be assigned to one or the
102 other, arbitrarily. It should probably pick the closest (longest) album name.
103 (I'm not sure that it can do this reliably, though, since the scan stage
104 runs in an undefined order.)
106 * The plugin doesn't do anything special to handle photos with similar names.
107 If you have `p100.jpg` and `p100.png`, one will get a viewer page called
108 `p100` and the other will be ignored. (I'm not sure what we could do better,
111 * If there's no `albumimage` in a viewer page, one should probably be appended
116 * The generated viewer page should extract as much metadata as possible from
117 the photo's EXIF tags (creation/modification dates, author, title, caption,
118 copyright). [[smcv]] has a half-written implementation which runs
119 `scanimage` hooks, and has an `exiftool` plugin using [[!cpan Image::ExifTool]]
120 as a reference implementation of that hook.
122 * There should be an option to reduce the size of photos and write them into
123 an underlay (perhaps just the transient underlay), for this workflow:
125 * your laptop's local ikiwiki has two underlays, `photos` and `webphotos`
126 * `photos` contains full resolution photos with EXIF tags
127 * for each photo that exists in `photos` but not in `webphotos`, the album
128 plugin automatically resamples it down to a web-compatible resolution
129 ([[smcv]] uses up to 640x640), optimizes it with `jpegoptim`, strips out
130 all EXIF tags, and and writes it into the corresponding location
132 * `webphotos` is what you rsync to the web server
133 * the web server's ikiwiki only has `webphotos` as an underlay
135 * Eventually, there could be a specialized CGI user interface to batch-edit
136 all the photos of an album (so for each photo, you get an edit box each for
137 title, author, copyright etc.) - this would work by making programmatic
138 edits to all the `albumimage` directives.
