The particle is failing to retrieve the first image from any given article.
It is worth noting that we load images directly in the text, not through Joomla's intro / full image fields.
In addition, we are using Flexicontent.
With other extensions we've used this is usually not a problem, since Flexicontent stores the data of each article on the default #_content table-
A typical image tag looks like this.
<p><img style="margin-right: 5px; margin-left: 0px; float: left;" alt="newsletter" src="/images/stories/flexicontent/s_emsa_newsletter.png" /></p>
All other details are picked up correctly (title, text, date and so forth).
