open function.html_image.php from plugin directory.

note: height & width will be added to <img> tag

add this:
=======================

Code:

case 'path':
if(!is_array($_val)) {
   $_key = smarty_function_escape_special_chars($_val);
} else {
   $smarty->trigger_error("html_image: extra attribute '$_key' cannot be an array", E_USER_NOTICE);
}

if (empty($_key)) {
   $smarty->trigger_error("html_img: missing 'path' parameter");
   return;
}

if (is_file($_key)) {
   //set image file link
   $file = str_replace($_SERVER['DOCUMENT_ROOT'],"",$_key);

   //get image height & width
   list($width,$height)=getimagesize($_key);

   //set params
   $params['width'] = $width;
   $params['height'] = $height;
}
else {
   $smarty->trigger_error("html_image: unable to find '$_key'", E_USER_NOTICE);
}
break;

=======================

right after this lines (line 70):
=======================

Code:

case 'alt':
         if(!is_array($_val)) {
            $_key = smarty_function_escape_special_chars($_val);
         } else {
            $smarty->trigger_error("html_image: extra attribute '$_key' cannot be an array", E_USER_NOTICE);
         }
         break;

=======================

now you can use {html_image path='full_path_to_file'} in your template pages.

i found this very useful when checking if image file exist:

Code:

$imgFile = "path_to_img";

if (is_file($imgFile)) {
//return full path to image
//no need to change to document root url
$smarty->assign( 'image', $imgFile);
}

then in smarty

Code:

{if $image !=''}
{html_image path=$image}
{/if}

enjoy!
