Noise Ninja plug-in for Photoshop on PowerPC Mac

Version 2.3.2

For OS X 10.5 and later (Leopard, Snow Leopard, and Lion), click here to download the plug-in. For OS X 10.4 (Tiger), click here
Unzip (decompress) the downloaded file if your web browser didn't automatically unzip it already. Right-click or option-click on the file and choose "Open With -> Archive Utility". (If you use Stuffit Expander, you must have version 8.0.2 or later or the file will not unzip correctly.)
Drag the entire decompressed folder to the Plug-Ins directory in Photoshop. Photoshop is usually located in the Applications directory, and the Plug-ins folder is inside of the Photoshop folder. (If you have a previous installation of Noise Ninja, remove it from the Plug-ins folder before adding the new version.)
Restart Photoshop and open an image. Go to the Filter menu. You should see a submenu labelled "PictureCode", with an item "Noise Ninja". Select it to launch the plug-in.

If you do not see the PictureCode menu, make sure you are not accidentally running the 32-bit version of Photoshop. Some editions of Photoshop install both 32-bit and 64-bit versions (one under "C:/Program Files (x86)" and the other under "C:/Program Files"). To determine which version you are running, go to the System Info dialog (in the Help menu) in PhotoShop. The first line should display the version number and end with "X64". If you don't see "X64", you are probably running the 32-bit version.

When the plug-in is running, you can access help, preferences, and license information through the menu bar at the top of the plug-in window. A PDF version of the help is available in the "doc" folder.
If you have purchased a license, go to the plug-in's Help menu and select "Install and view license..." to unlock the software. You MUST enter BOTH the "User name" and "Keycode" exactly as sent to you.
