What can this extension do?
Allows users to create frames and tables with lists of News per Category, limited to n elements. With thumbnails preview!

You can chose several types of previews: simple text, icons in colums, icons with text preview. NewsZ browse also subcategories and may be a true "news aggregator.

To mark the text inside article for preview, simply use this syntax: &lt;!--NewsZ--&gt; ... here the text article preview ... &lt;!--EndZ--&gt;

You can hide a preview text in article: &lt;!--NewsZ ... here the hidden text for article preview ... EndZ--&gt;

You can also hide a icon preview in every article: &lt;!-- --&gt;
