azett 52bf429a01 Replaced Smarty 2.6.31-dev with v 4.0.4, keeping the FP-specific Smarty plugins.

Updated calls to current Smarty API (register_function()/register_modifier()/register_block() -> registerPlugin(); assign_by_ref() -> assignByRef()).
Fixed file includes in templates with quotes.
Removed SmartyValidate.class.php includes.

Still work in progress as some errors still appear!

{html_image}

{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.

Attribute Name Type Required Default Description

    file        string     Yes              *n/a*          name/path to image
   height       string      No      *actual image height*  Height to display image
   width        string      No      *actual image width*   Width to display image
  basedir       string      no      *web server doc root*  Directory to base relative paths from
    alt         string      no              *""*           Alternative description of the image
    href        string      no              *n/a*          href value to link the image to
path\_prefix    string      no              *n/a*          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 securty policy. See the Security 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, it is generally better to avoid {html_image} and leave image tags static for optimal performance.

{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:

<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" />
