OK, did I get you right? The Articles Category modul inherits the global style from blockk template and therefore the images display fully in that section. Then, could you please help to change this?
E.g. to customize style for Articles Category module that way that it looks like in the Article - Latest Module, with little thumbnails. If that´s not easy, maybe it is possible to change global style, so the default style use the intro image.
Unfortunately the JA Content Listing module can not do the same as the joomla standard module. With Articles Category module it is possible to use dynamic mode. It will dynamically display the list of matching articles, if existing, within the apropriate Category accordingly. As far as I can see, it is not possible to do that with JA Content Listing module.
