Is there anyway to move several small pictures on top of another big picture in GUI? Those small pictures need to move in some velocities(pixels/s), which can be adjusted by users.

Thank you so much for helping!

image() the second picture into existence after drawing the first, and record the handle of the image. Then to move it, you can set its XData and YData property.

If the "several small pictures" move rigidly to each other then you could create a single larger image that contains them all, and set the Alpha property of the image() object to 0 in the places where the top images were not to appear.
