SplashImage Effect

[notta]

I remember seeing a thread a while back where someone wrote this amazing effect where the splashimage would dissolve onto the screen. I forget who was the author, but I thought it was GaryFrost. I can't seem to find the thread through the search tool. Does anyone know which one I'm talking about and if so, do you have the link for it? Thanks.

#include <WinAPI.au3>

;~ Splash
Global Const $AC_SRC_ALPHA = 1

_GDIPlus_Startup()

$pngSrc = "splash.png"

$hImage = _GDIPlus_ImageLoadFromFile($pngSrc)
$width = _GDIPlus_ImageGetWidth($hImage)
$height = _GDIPlus_ImageGetHeight($hImage)

$Splash = GUICreate("", $width, $height, -1, -1, $WS_POPUP, $WS_EX_LAYERED, $DS_MODALFRAME)

GUISetState(@SW_LOCK)

SetBitmap($Splash, $hImage, 0)
