Problem displaying latest image on post

No image is specified: <img alt="Latest Blog Post" src="" style="outline: 1px solid rgb(255, 0, 0);">
src=”” should have an image URL (src=”https://www.adriaalsina.com/path/to/image/image.jpg”)

This is the HTML that is being output:

<!-- begin latest post -->
<div id="latest">
	<div class="l">
	<h3>Latest Blog Post</h3>
	<img src="" alt="Latest Blog Post" />
	</div>

Did you forget to upload an image for this post?

The code line reads <img src=”” alt=”Latest Blog Post”>, which clearly indicates there’s no image, but I can’t edit the body of the template, what shall I do?

Thanks!

Sorry, I’ve found how to edit the code now, but still can’t see the bug, could anyone take a look at it? Thanks!

<!-- begin latest post -->
<div id="latest">
	<div class="l">
	<h3>En portada</h3>
	<img src="<?php dp_attachment_image(0, 'full', '290', '180'); ?>" alt="En portada" />
	</div>
	<div class="post">
	<h2><a>"><?php the_title(); ?></a></h2>
	<div class="noimage"><?php the_content('? Read More'); ?></div>
	</div>
<div class="break"></div>
</div>
<!-- end latest post -->
