i need instructions on how to install plugins for infranveiw, gimp2.2 and paint.net?

Answer 1

Here you go.

Irfanview PlugIns
http://www.irfanview.com/plugins.htm

Gimp Plugins
http://docs.gimp.org/en/concepts-intermediate.html#gimp-plugins-install

Can find info on the Paint.net plug ins. It may depend on the plug in as to which folder to put it in.
