I decided to create some Windows Vista Style 256x256px Icons for Fast Dial based on a post from mafi0z here.
NOTE:THESE ARE ICONS THAT ARE USED BY WINDOWS, NOT FAST DIAL LOGOS, FOR THEIR LOGO VERSIONS, SEE THE TEXT AFTER EACH LOGO

1. Basic Fast Dial Logo (by k-dash (Large version by mafi0z))

Logo here.
Icon here.

2. Fast Dial Folder

Logo here.
Icon here.

These icons can be used for folders or by creating a shortcut with the target

Note: You may have to replace "C:\Program Files\Mozilla Firefox\firefox.exe" with the location of your Firefox process if you haven't installed it in the default location.

Looks cool on my RocketDock:

All these icons have been created with IcoFX, the free icon editor.

To admins: I wonder if you could upload the icons on UserLogos itself so that I won't have to upload it on another site and link it here.
