All sounds are fully configurable using an external XML file, which can be edited using any standard text editor, like Windows Notepad or Textpad. / All image descriptions, paths, and category names and images, are fully configurable in the XML configuration file. / All gallery text is fully configurable, for example the top gallery title, and the category text. You can even use so-called "bb-code" like [b] and [i] to insert italic and bold effects. / 3 possible image transitions are available: horizontal wipe, vertical wipe, or both horizontal and vertical wipes. The demo shows both horizontal and vertical wipes enabled ("B" setting in the XML configuration). / Tooltip effects are available (but can be disabled easily in the XML configuration file). / Image popup feature allows you to link any image to a popup window (an external HTML file, which comes with the gallery code). / Thumbnail and image folders can be specified in the XML file. It's also possible to use the same folder for both, if you don't feel like creating a bunch of separate thumbnails. / 100% of the Flash 2004 Pro. source code is included with your purchase. Thus, if you can't find an XML option to do what you need, you can always just directly modify the Flash code, provided that you have the Flash 7 authorinig environment. / Infinitely many categories are possible, and infinitely many images per category.
