Wrong. If you call BringToFront on Imagebox3 then it will be brought to the front, so in front of every other control. If you then call BringToFront on Imagebox4 then it will be brought to the front of evey other control including Imagebox3. If you call BringToFront on every control the the first one you call it on will be at the back and the last one will be at the front. The opposite is true of SendToBack. Just imagine that the controls are a pack of cards. If you bring each of the 52 cards to the front, one after the other, then the first one would be end up the back.
