-* [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]]
+When a viewer page is generated or inlined into an album, the template can
+contain these extra variables:
+
+* `<TMPL_VAR ALBUM>` - page name of the album
+* `<TMPL_VAR ALBUMURL>` - relative URL to the album
+* `<TMPL_VAR ALBUMTITLE>` - title of the album, usually taken from
+ a [[ikiwiki/directive/meta]] directive
+* `<TMPL_VAR CAPTION>` - caption for the image
+* `<TMPL_VAR THUMBNAIL>` - a small [[ikiwiki/directive/img]] for the image
+* `<TMPL_VAR IMAGEWIDTH>` - width of the full-size image in pixels
+* `<TMPL_VAR IMAGEHEIGHT>` - height of the full-size image in pixels
+* `<TMPL_VAR IMAGEFILESIZE>` - size of the image, e.g. `1.2 MiB`
+* `<TMPL_VAR IMAGEFORMAT>` - format of the image, typically `JPEG`
+
+The template for the viewer page can also contain:
+
+* `<TMPL_VAR IMG>` - a large [[ikiwiki/directive/img]] to display the image
+* `<TMPL_VAR PREV>` - a link to the previous viewer, typically with a
+ thumbnail
+* `<TMPL_VAR NEXT>` - a link to the next viewer, typically with a
+ thumbnail
+
+## Including album entries elsewhere
+
+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:
+
+ \[[!inline pages="..." sort="-age" template="albumitem"]]
