You are using GIMP, are you not? Well. Begin with extracting the rar or zip file. If it's in it, that is. Extract it to Gimp/2.0 or something like that in your directory. There is an etc. or something of that such. Inside it will be a folder called brushes. Extract them there. If they are just normal brushes, that didn't come in Rar or Zip, just cut and paste it to there.
Okay, thanks for helping me out. Besides that, I was wondering, when I'm on the page for downloading the brushes, and it says like 'Crazy Brushes' or 'Splatter brushes' etc, how do I donwload them from there?
