One of Paint Shop Pro's most versatile features is it's ability to accept Adobe compatible plugins. These plugins are invaluable, whether  you're creating webgraphics, or just touching up photos. Though there are many commercial plugins (such as Alien Skin), there are even more free plugins available for download. Most plugins have a number of settings that you can vary, so the possibilities are limitless. I have well over 50 megabytes of filters on my computer. And even though I can't claim that I use all of them, just having them available is a constant source of inspiration.
 

Filter Factory Galleries

These are the most well known filters on the web. If you want to create webgraphics, you MUST have these. Many of my tutorials use Filter Factory plugins. The galleries used to be available in the .8bf format that Paintshop uses, but they are now compiled into more compact FFL files. To decompile them you'll need Harry the Raver's Plugin Commander PiCo, which you can get at The Plugin Site.
 
 

Greg's Factory Output Filters

Greg's Factory Output Volumes I and II are probably the filters I use most aside from FFG. His Pool Shadow filter is a great compliment to the one found in FFG A, and his Metal Effects filter is truly unique. Greg doesn't seem to be on the net anymore, but you can get his filters on my main tutorials page. Just look for the link right after the tutorials list

Andrew´s Filter Collections

Andrew Buckle has created a unique collection of filters, many designed to cause unusual color changes. Like the Filter Factory Galleries, these are compiled in FFL format, and require Plugin Commander to make them usable (it's in the Tools section). His galleries are up to 62 now and there's no sign of his ever stopping. But I don't have the patience to list them all. The ones beyond 35 can be reached from any of the pages below.
 
 
 

Kangaroo's Homepage

Kang's filters have to be seen to be appreciated. Almost more interesting than the filters themselves are the names he gives them. I think my favorite is ben-wah's Sister.
 
 

DC Special Plugin Filters

A great set of filters. The Persian Rug filter is wonderful for creating intricate patterns for sidebars, and the PatternEdit Do and Undo filters are a must for anyone working on background textures. You can download DC Special 4 from Dennis Crombie's Homepage. GraphoManiac has kindly kept sets 1-3 up and available, and they can be downloaded from the PSP Resources page. You can view a gallery of the effects in 1-3 here.
 
 

Abstract Dimensions (formerly Webweaver XXI)

This is a set of three filters created especially for Paint Shop Pro by Sandy Blair. The set includes a pallette mapper, a ripple filter, and a directional embosser.
 
 

Krusty's Graphic Home Page

Krusty (Thomas R. de Massy) has put together a wonderful collection of filters. There are three volumes: a group of transparency editors, an incredible set of pattern generators, and a set of retouching tools.
 
 

CPK Collection by Chris Kendall

Available at PC Resources for photoshop. Just scroll down the page a bit to find these two sets.
 
 

BladePro BladePro is an incredible Plugin that combines bevels with textures and colors. This plugin is one that you absolutely have to try. It's Shareware, with a 15 day expiration date, but the registration fee is only $49 - and it's worth every penny.
 

Other Filters
 
 

I also want to alert you to three great resources for plugins:
 

GrafoManiac This site maintains a great list of available filters, as well as previews of many of the effects. In addition, many of the free filters are available for download on-site. The Plugs 'n Tools section is where you'll find what you need.
 

Pluginhead: Filter Factory Compendium. Another great collection of filter links. Go to the main page here and admire the babe with the wires in her skull.
 

The Filter Factory List at Premiere Plugin HQ A list of ALL of the free filters made using the Filter Factory, and where to get them.
