First, select the digital photograph that you want to use as your PC Wallpaper in the ThumbsPlus main viewing area. (Click the image below for a larger view.)
Next, from the Image menu on the main toolbar, select Wallpaper.
There are four options from which you can choose when creating the wallpaper:
Tiled – With this option, the photo will be tiled across the background of your display. This is a good choice to pick if the image you are working with is small and you want the entire display area to be filled with copies of the smaller photo. See the screenshot below for an example of this.
Centered – Choosing this option will center the photo on your screen. If the dimensions of your photo are smaller than your screen resolution, there will be “leftover” space around the edges of your image (see screenshot below). Likewise, if the dimensions of your digital photo are larger than your resolution, only the center part of the photo that “fits” will be displayed.
Stretched – Whether the dimensions of your photo are larger or smaller than your screen resolution, you can use this option to resize the image to fill most all of your display while maintaining the aspect ratios (the relation between height and width) of the photo. One thing to note here is that if the aspect ratios of your photograph are different from your screen resolution, then you will still have some leftover space either on the vertical or horizontal edges of your display when using this method.
Fully Stretched – The only difference between this option and the Stretched alternative is that you don’t have to maintain the aspect ratios of the photograph when choosing this method. So, this is the method to use if you want the entire photo shown in the wallpaper and the wallpaper to completely cover the display area.
