svBuilder is a desktop application that allows you to easily build SimpleViewer galleries. svBuilder will automatically resize images, generate thumbnails and create the required XML and HTML embed code.
Presets allow you to easily save and load gallery configuration options. Once you have customized your gallery to your liking, you can save the current gallery config options as a 'preset'. A preset is an XML file, similar to the gallery.xml file that contains a list of config options.
