Technicolor 2 Color Script

Don't you get a dialogue, when you click on the attachment, where to save the file? If this doesn't work, try clicking on it with the right mouse button (Do Macs have one meanwhile?). You will get a context menu where you can pick the "Save Link As" option. Save it somewhere in your homefolder, default should be "~/Download". Then you have to put it in the scripts folder of GIMP. There should be two scripts folder, one general for all users (that's why you don't have write permission there) and one in your home folder. It's better to use the second one. Open a file browser and go to your home folder. Switch the hidden folders option (somewhere under 'view' or 'option'). You will see now a folder named ".gimp-2.4". The dot before the folders name means, that it is a hidden folder. Open the ".gimp-2.4" folder. Now you should see several folders, among others the scripts folder. Open it. Here you can put in the scripts, you downloaded. Then (re)start GIMP. When you open a picture, you should find now a new option eg. in Filters -> Generic -> National Geographic. I hope, I'm right, because I have no experience in Macs because I'm a Linux user. But Mac should behave similar since it's a BSD derivative. Good luck with that.
