Go to Configure -> System Preferences in the admin interface menu, look for the "Zoom enabled for images in article content?" setting and mark Yes.
If disabled, article images will still be displayed but they won't be clickable to zoom.
When enabled output generated by Newscoop for images inserted in article body will look like this:
<a href="<url_to_original_size_image>" class="photoViewer" title="">
<img src="<url_to_image_resized_by_editor>" border="0">
There has been error in communication with Booktype server. Not sure right now where is the problem.
