Problem with the_excerpt

Hello,

In one of my posts, I have specified a url to an image for the excerpt.

Now when I use the the_excerpt() function to fetch that url:

<li><img src="<strong><?php the_excerpt();?></strong>" alt="" /></li>

…the following happens:

<img src="<p>https://localhost/includes/assets/img/folio/eenappje.png</p>" alt="">

As you can see, a “<p>” and “</p&gt” are added to the beginning and end of the url.

How can I stop this?

Thanks.
