This simple Paint Shop Pro tutorial will show you how to create attractive grids on your images.
Open up Paint Shop Pro, and the image you want to work with.
Go to Effects > Texture Effects > Tiles.
A menu will come up. Match your settings to mine:
Using your keyboard, press the ‘Ctrl’ key and hold it down until after you press the ‘C’ key once. Let go. Then press ‘Ctrl’, hold and then ‘Z’ in the same way. Now press ‘Ctrl’ and hold, then press ‘L’. This will paste the squares on top of your original image in a layer.
Go to Layers > Properties, and it change the Opacity to about 10%. Press ‘Ok’ and save.
