Image names and captions, and category ("group") names, are easily configurable using an external XML file, which can be edited using any good text editor, like Textpad (www.textpad.com). Over a dozen XML configuration options are available in the external XML configuration file. Background JPG image is loaded externally, so it can be modified or changed easily. This image must be a non-progressive JPG image. Includes 100% of the Flash 2004 Pro. (Flash 7) source code, including the .fla file and all .as files. All sounds are external MP3 files, loaded at run-time into the gallery, which means that you can easily replace them with your own MP3s. All images are external, non-progressive JPG images, one folder per category (note: the XML configuration must match the folder hierarchy). Sleek thumbnail viewer and category changer was custom-designed by Flash guru Michael Klishin. Rollover effects are present for thumbnails and arrow scrollers.
