[[!template id=plugin name=img author="Christian Mock"]]
[[!tag type/chrome]]
This is an image handling plugin. While ikiwiki supports inlining full-size
images by making a [[ikiwiki/WikiLink]] that points to the image, using
this plugin you can easily scale down an image for inclusion onto a page,
providing a link to a full-size version.
This plugin uses the [ImageMagick](http://www.imagemagick.org/) tools via
[PerlMagick](http://www.imagemagick.org/www/perl-magick.html).
Note that this is a stripped down version of Christian Mock's
[[original_img_plugin|contrib/img]].
## usage
\[[!img image1.jpg size="200x200" alt="clouds"]]
The image file will be searched for using the same rules as used to find
the file pointed to by a [[ikiwiki/WikiLink]].
The `size` parameter is optional, defaulting to full size. Note that the
original image's aspect ratio is always preserved, even if this means
making the image smaller than the specified size. You can also specify only
the width or the height, and the other value will be calculated based on
it: "200x", "x200".
You can also pass `alt`, `title`, `class` and `id` parameters. These are
passed through unchanged to the html img tag. If you include a `caption`
parameter, the caption will be displayed centered beneath the image.
The `link` parameter is used to control whether the scaled down image links
to the full size version. By default it does; set "link=somepage" to link
to another page instead, or "link=no" to disable the link, or
"link=http://url" to link to a given url.
You can also set default values that will be applied to all later images on
the page, unless overridden. Useful when including many images on a page.
\[[!img defaults size=200x200 alt="wedding photo"]]
\[[!img photo1.jpg]]
\[[!img photo2.jpg]]
\[[!img photo3.jpg size=200x600]]
