Just use any image editor, like Photoshop or whatever, make your image like it shows in the tutorial and just save it as a .bmp image. Then, go to your desktop and with desktopX running, right click the desktop, choose "DesktopX" from the menu then "new Object". then you can configure the object to show your image. Remember to set all the parameters, including how many frames in the image etc. If you get stuck, just right click an existing zoomer, choose "properties" and look at all the parameters set for
that image. That's how I learned to make them.
Have fun!!
