1. Download some PSP scripts! (always a good start...)
2. Extract the scripts if they are in .Zip folders. (Right click > Extract all)
3. Now go to PSP... my scripts are for PSP11 so make sure you have the right version of PSP!
4. Take an image, any image you like.
5. Now go to File > Script > Run...
6. Find one of your scripts and click 'OK' and let the script do it's work! If any windows come up click 'Ok'.
7. That's it!
