The SimpleGallery plug-in generates online exhibitions from Sets that you create. By default, this page displays Sets of the type "exhibition." To display Sets of another type, configure the type name next to simpleGallery_set_type in the simpleGallery.conf file in the simpleGallery plugin folder. You can replace this text by editing the intro_text_html.php file in your theme folder in the SimpleGallery plugin directory.
You can provide introductory text for your galleries by entering a Set Description in the Set editor. A thumbnail image is automatically generated from the first record in your Set.
