Photoshop - By KDEWolf
(NOTE: Photoshop 7.00 turns alpha channels into transparent, what sucks, so be sure to get 7.01 patch ASAP! If for some reason you can't upgrade, there is a plugin that fixes this. Found Here - Thanks to Larkas for the Plugin!)
1. Open the skin file
2. Click 'Channels' int the layers panel
3. Select 'Alpha 1'
4. then just edit (notice you'll edit grescale, where black is transparency and white opaque, allowing variations)
TIP: The 'eyes' at the left of the channels and layer names show and hide the layer/channel.
