A sleek, book-style interface design make this gallery unqiue. Categories and images are arrayed vertically, and infinitely many categories and images are possible. Categories and images can be added, removed, and re-organized easily by editing an external XML configuration file. Textpad (www.textpad.com) or other common text editors can be used to edit the XML file. Bold, italic, and underline can be used with [b], [i], and [u] tags in the XML file. All sounds are externally loaded from MP3 files, so you can change them easily. All images are loaded into the SWF as external JPGs. These must be non-progressive JPG images. External XML configuration file allows you to quickly modify the gallery settings without requiring knowledge of Flash. The XML file is editable using most text editors, like Textpad (www.textpad.com). 100% of the Flash 2004 Pro. source code is included with your purchase, including all .fla and .as files. If you can't find an XML configuration setting to do what you need, you may be able to make the necessary modification by editing the Flash source directly.
