The "download file" button should be right next to these comments. It's an ABR, meaning it's a brush. (Duh.). After you download this and any other brushes you want, put them in the custom brushes folder in your Photoshop file directory. You can then open Photoshop, select the brush tool, go up to change your brush, and say "Load custom brushes". Then you will click on this file. You can now make streams of lightning in Photoshop, that's how it works for me.
