Can someone be kind and try the following code and images?
SetImageMask only works with "Brick_hole.png", the others is not working.
The images that are supposed to "mask", make holes in the destination image is completely transparent, and the remaining pixels are white. (RGB 255,255,255)
But as I said, it works only with one of the pictures ???
What have I missed?

Has fixed the source code and put all the images in the same image.
Think I've got a little hang of this now!
Here comes a new test source.

// set display properties

// load in and separate the images
SetFolder("/media")
MyImg = LoadImage("Brick_hole.png")
bigBulletImg = CopyImage(MyImg, 0, 0, 64, 64) // Bullet hole
brickImg = CopyImage(MyImg, 64, 0, 64, 64) // Bricks
greenBox = CopyImage(MyImg, 128, 0, 32, 16) // Little Green box.
whiteCross = CopyImage(MyImg, 128, 16, 16, 16) // White cross
bombMask = CopyImage(MyImg, 128, 32, 8, 8) // white bomb mask
// To view the images separately,
// to see clearly what is happening,
// and which pictures are used.
bulletSprite = CreateSprite(bigBulletImg)
SetSpritePosition(bulletSprite, 64, 64)
brickSprite = CreateSprite(brickImg)
SetSpritePosition(brickSprite, 64, 128)

SetSpritePosition(greenSprite, 64, 192)
crossSprite = CreateSprite(whiteCross)
SetSpritePosition(crossSprite, 64, 208)
bombSprite = CreateSprite(bombMask)
SetSpritePosition(bombSprite, 64, 224)
