For those of you who use GIMP, you know it is a really great alternative to Photoshop. Like any program, free or not, there is always room for improvement. Plugins are a an easy way to add functionality.
GIMP has two different types of plugins, Script-fu and Python-fu. Right out of the box, you can add Script-fu plugins. To add Python based plugins, there is some additional steps and add-ons needed.
Get Some Plugins
To find more plugins than you can shake a tick at, go to the GIMP Plugin Registry. The different plug-in scripts are tagged pretty well so you can type in the keywords for what you are looking for in the search bar to the right side of the page.
When you find something that catches your eye, download it by clicking on the link usually at the bottom of the page. The file should end in [.scm].
1. Pencil Draw
Pencil Draw is a a pretty cool effect. It is fun for the occasional profile picture. In a nutshell, the pencil draw plug-in traces the outline of the main shapes and fills in the open areas with a gray shading.
To use this effect, select the area you’d like to change then select Pencil Draw from the filters menu.
