You can set the image resultion by changing the values at the bitmap level using the following API calls (Which is more Cesar's forte)

Declare Long GdipGetImageHorizontalResolution In GDIPlus.Dll ;
			Long nativeImage, Single @ resolution
		Declare Long GdipGetImageVerticalResolution In GDIPlus.Dll ;
			Long nativeImage, Single @ resolution
		Declare Long GdipBitmapSetResolution In GDIPlus.Dll ;
			Long nativeImage, Single xdpi, Single ydpi
