+# {html_image}
+
+`{html_image}` is a [custom function](index.md) that
+generates an HTML `<img>` tag. The `height` and `width` are
+automatically calculated from the image file if they are not supplied.
+
+## Attributes
+
+| Attribute Name | Required | Description                                                             |
+|----------------|----------|-------------------------------------------------------------------------|
+| file           | Yes      | name/path to image                                                      |
+| height         | No       | Height to display image (defaults to actual image height)               |
+| width          | No       | Width to display image (defaults to actual image width)                 |
+| basedir        | no       | Directory to base relative paths from (defaults to web server doc root) |
+| alt            | no       | Alternative description of the image                                    |
+| href           | no       | href value to link the image to                                         |
+| path\_prefix   | no       | Prefix for output path                                                  |
+
+-   `basedir` is the base directory that relative image paths are based
+    from. If not given, the web server's document root
+    `$_ENV['DOCUMENT_ROOT']` is used as the base. If security is
+    enabled, then the image must be located in the `$secure_dir` path of
+    the security policy. See the [Security](../../programmers/advanced-features/advanced-features-security.md)
+    section for details.
+
+-   `href` is the href value to link the image to. If link is supplied,
+    an `<a href="LINKVALUE"><a>` tag is placed around the image tag.
+
+-   `path_prefix` is an optional prefix string you can give the output
+    path. This is useful if you want to supply a different server name
+    for the image.
+
+-   All parameters that are not in the list above are printed as
+    name/value-pairs inside the created `<img>` tag.
+
+> **Note**
+>
+> `{html_image}` requires a hit to the disk to read the image and
+> calculate the height and width. If you don't use template
+> [caching](../../programmers/caching.md), it is generally better to avoid `{html_image}`
+> and leave image tags static for optimal performance.
+
+## Examples
+
+```smarty
+{html_image file='pumpkin.jpg'}
+{html_image file='/path/from/docroot/pumpkin.jpg'}
+{html_image file='../path/relative/to/currdir/pumpkin.jpg'}
+```
+
+Example output of the above template would be:
+
+```html
+<img src="pumpkin.jpg" alt="" width="44" height="68" />
+<img src="/path/from/docroot/pumpkin.jpg" alt="" width="44" height="68" />
+<img src="../path/relative/to/currdir/pumpkin.jpg" alt="" width="44" height="68" />
+```
