I'm working on registration form and use a simple captcha php script to generate captcha image.

This is the html code used to display the captcha image on the page

<img id="img" src="captcha.php">

Everything worked fine on the static version of the page, but the image doesn't show on Wordpress generated page.

Is it possible to display my captcha image in Wordpress page without using any plugins ?

EDIT: I'm adding a bit more of my code

My page.php file

<?php get_header(); ?>
<?php while ( have_posts() ) : the_post(); ?>
  <div class="row">
    <div class="col-md-9 col-left-outer">
        <div class="col-md-12 col-left">
            <img id="img" src="'.home_url().'/captcha.php"> <-- Added this line to test if captcha will display from page.php file -->
            <?php the_content(); ?>
    <div class="col-md-3">
        <div class="col-md-12 col-right">
          <!-- Archive Side Navigation -->
            <?php get_sidebar(); ?>
 <!-- /.row -->
<?php endwhile; wp_reset_query(); ?>
<?php get_footer(); ?>

The code I input in the textbox in Wordpress dashboard

<div class="row">
   <div class="col-lg-4 col-md-4">
      <label for="InputName">Παρακαλούμε, εισάγετε CAPTCHA</label>        
      <img id="img" src="'.home_url().'/captcha.php">
      <input id="captcha1" class="form-control" name="captcha" type="text" required>

    Since WP uses .htaccess to rewrite, you should not use a relative path as in
    src="captcha.php", but an absolute path like
    src="" or

    You will have to adapt the paths above to your configuration.

    WP knows where your site is located, so to be independent, use something like:

    echo '<img id="img" src="' . home_url() . '/captcha.php">';


    <img id="img" src="<? php echo home_url() ?>/captcha.php">

    <?php will only work if in a plugin or template. If your html code is only in a WP Widget text Content, the PHP will not be parsed for security reasons.
