It's easy to install a desktop widget, first make sure that you have the Yahoo Widget Engine v4.5,
if you don't have the Yahoo engine you can download it from here.
Then download the widget and save it to your hard disk.
This is the icon of the widget, search for the widget at the place where
you saved it and double-click to open it. A dialog window will open with a warning message that the widget was not built by Yahoo
Unfortunatelly we can't certify our widgets with Yahoo, as they are related with adult sites.
Proceed by clicking the Use Widget button and you're done, now your widget is installed and it appears on the widget dock from where you can access it from now on.
If you have selected the Dock option to consolidate the widgets, then the Dock will move the widget in the My Documents/My Widgets folder.
Note:
Some browsers (like Safari for Windows) add the ".html" extension to the name of the downloaded file. Just delete the ".html" extension and double click to use it.
