{html_image} is a
custom function
that generates an HTML <img> tag.
The height and width
are automatically calculated from the image file if they are not supplied.

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, the path to the image must be within a
secure directory.
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.
Technical 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,
it is generally better to avoid {html_image} and leave
image tags static for optimal performance.
