Okay, just to clarify. The sample .json and .xml files contain the information that is displayed based on the configuration that is loaded by the config.json or config.xml files. So, if I want an external url to be linked to an image the same way that the news gallery setting will link to an internal article and I want it to look the same, I need to create a config file that describes what information will be loaded and then a file with content to load. Is this true?
If so, I'm not sure this will work anyway since when changing the source content to .xml or .json the module states the source is not compatible with the news gallery portal.
There must be an easier way. I'm using storebox for an arts org here in the states and want use sponsor logo images to open up to sponsor (external) websites.
