Hi sling19,
<blockquote>Anyone could tell me how to configure the intro images 200px*200px, and 660px*300px in latest news module, and 660px*300px shown in articles???each of them need to configure separately?</blockquote>
You can configure both of them in the backend of Joomla article (Images & Links tab).
<blockquote>2. joomla! will not automatic generate the 200px*200px thumbnail, after i insert 660px*300px in articles? 3. if not, how can i get the 200px*200px thumbnail??? </blockquote>
Thumbnail image will be automatically generated & displayed with 200x200px because we inclued our overriden layout of Article Category module on vertical view. So that, you just need to select your intro image only.
But, on hozirontal view, the thumbnail image will display the orgional size of full article image. So that, you need to insert the full image (at least 660px width, 300px height) into Joomlar content article.
