I've been meaning to publish a Photoshop 3rd Party Plugin.. to show how it's done.
I've had naysayers come on here and claim "Plugins don't work".. blah blah blah.
Anyhow.. sometimes.. you can simply copy the Plugins into PhotoshopPortable. Sometimes.. it requires additional work such as registry keys, licensing, etc.
Each Plugin is different and it's up to you to figure it out.
