Paint Shop Pro : Importing Brushes
This tutorial will show you how to import image packs in PSP. This can even work for Photoshop brushes.

I'll be using this image pack to demonstrate.

Step 1:
Paste the image pack into psp.

Step 2:
Select the free hand selection tool.


Step 3:
Make a selection around one of the brushes. [screenshot]
Now right click on the selection, copy, and paste as a new image. The brush should now stand alone as a separate image.

Step 4:
To be able to use this brush go to file > export > custom brush. A prompt will show up. Name the brush, then click ok.
You should now see the brush where the brushes are located.
