Painting Kit Help

[The chaser]

How do i install these plugins... i figured it might be them, but i couldn't get how to install them. Where should i extract them?

It says i can manually copy the plugin to the GIMP plugin directory. Do you know which files are the plugin?

Go where you had the painting, and replace my files with yours.

In the Gimp folder, search for a folder named "Plug-Ins". Install the add-on there
