// Define the function that implements the plugin

{
    $src = $params['src'];
    // Based on $src decide here if you want lightbox or not
    $lightbox = TRUE;       // or FALSE

    // Generate the <img> element
    // Get information from $params, put default values, do whatever you want
    $output = implode(' ', array(      // build the string from pieces
        '<img',

// Register the plugin in Smarty

<img src="filename.jpg" width="40" alt="bla-bla" etc>
