Path to images

Hi all, I’m new on wordpress, this is my first website.
My problem is the following, I’ve created plugin and added it to my wordpress, but my plugin have images that I want display in the page.

I’ve tried different way and I’m still not able to show the images.
My images are in the following path:
C:\wamp\www\wordpress\wp-content\plugins\aline\images

I’ve tried put these options in my HTML but none of them work:
<img src=”<?php bloginfo(‘template_url’); ?>/images/publico1.png” alt=””>
<img src=”<?php echo get_template_directory_uri() ?>/images/publico1.png” />
<?php echo ‘<img src=”‘ . plugins_url( ‘images/publico1.png’, __FILE__ ) . ‘” > ‘; ?>
<?php echo ‘<img src=”‘ . plugins_url( ‘images/publico1.png’, dirname(__FILE__) ) . ‘” > ‘; ?>

How can I do it, I’m doing something wrong?
Many Thanks
