How to limit post content and remove image caption from it

Hello,

I am using this function to limit the content in my themes. But the problem is whenever I call the function, it also displays the image caption. I want to remove the image caption when calling the_content_limit function.

Here is the code:

function the_content_limit($max_char, $more_link_text = '', $stripteaser = 0, $more_file = '') {

    $content = get_the_content($more_link_text, $stripteaser, $more_file);

    $content = apply_filters('the_content', $content);

    $content = str_replace(']]>', ']]>', $content);

    $content = strip_tags($content);

   if (strlen($_GET['p']) > 0) {

      echo "";

      echo $content;

      echo "&nbsp;<a href='";

      the_permalink();

      echo "'>"."Read More &rarr;</a>";

      echo "";

   }

   else if ((strlen($content)>$max_char) && ($espacio = strpos($content, " ", $max_char ))) {

        $content = substr($content, 0, $espacio);

        $content = $content;

        echo "";

        echo $content;

        echo "...";

        echo "&nbsp;<a href='";

        the_permalink();

        echo "'>"."</a>";

        echo "";

   }

   else {

      echo "";

      echo $content;

      echo "&nbsp;<a href='";

      the_permalink();

      echo "'>"."Read More &rarr;</a>";

      echo "";

   }

}
