Since the imagedownloader doesn't directly give you the bitmap, just call the CreateRoundRectBitmap method on the ImageView's bitmap afterwards:

    Dim myImage As ImageView = roundedImageView
links.Put(myImage, "http://www.b4x.com/basic4android/images/SS-2012-08-29_12.55.42.png")
myImage.Bitmap = CreateRoundBitmap(myImage.Bitmap, 40dip)
