+This folder holds the icons used by Algohol. The default.png icon is used as a default icon, while the other icons are used for specific pages.
+
+Example:
+The calculator is opened in Algohol. The links.php file in the previous folder links to calc.htm. What also happens here is that links.php looks for calc.png in the icons folder. If such a file is not found, it defaults to defult.png.
