A GIMP splash screen based on the Adobe Photoshop one.
There are 3 colour variations of the splash screen in the download (red, blue and green) and the GIMP .xcf file, so you can modify it yourself.
The GIMP title text is from http://www.clker.com/clipart-gimp-official-text.html
To install them, go to your .gimp-2.6 folder (it should be in your home folder) and if there isn't one already, create a folder called "splashes".
Put the splash screen you want to use in the folder, or put all of them in and it will choose one randomly when you launch GIMP.
