It's a module issue. For anyone who knows PHP and Smarty, it would be fairly easy to add in such a feature to a module, such as News or AMS. Just add a field to the article submission form where you can browse to the image, add a space in the DB to store the image name and pass the image name to the template. Then layout the news items however you want in the template, complete with image.
The issue is not XOOPS, it's the modules that are available, and the ability of your web master to work with the technology.
