I took a look, and this is what I see for that image:
<img src="/www.lacaradeotro.com/web/content/wp-content/uploads/media/appearance/footerlogo" title="lacaradeotro_logo" class="alignleft">
As you can see, the src value is not a valid URL for an image. First of all, it needs to start with http:// not, /www. Secondly, you are missing the extension on the filename. I do not know what the proper extension for that image is; I tried accessing it with a .jpg, .gif or .png and neither worked. Are you sure you uploaded that image? This is what the final URL should look like, for the source (an example):
http://www.lacaradeotro.com/web/content/wp-content/uploads/media/appearance/footerlogo.png
