Step 1 - Prepare the Background Image
Before preparing the background image, you need to decide the size of the slideshow. The size of the background image need to be slightly larger than that of the slideshow. The background image we used in this tutorial can be downloaded at Download Slideshow Background Image.
Step 2 - Add the Background Image into the Software and Adjust its Position
Now we can add the background image to the software, at Skins dialog, Background tab. Then we need to adjust its size and position by changing the value of Width and Top.
The value of Width and Top is in percent of the slideshow width and height. Normally, the value of Width is about 100 to 150 and the value of Top is about 0 to -50. Its best value is determined by the size of the slideshow and the size of your image. You need to adjust these two values carefully to get a better result.
In this tutorial, we choose the Width as 112 and Top as -35.
