In case you are talking about VCL
TSpeedbutton, you can place aTActionListon your form and connect it to yourTImagelist. Then create an action in the actionlist, set itsImageIndexto the desired image. Now connect theTSpeedbuttonto that action. In theOnExecuteevent of the action change the actionsImageIndexproperty to the new value. The speedbutton now shows the new image.
