Resizing the states of a custom button

thanks for the tutorial but it doesn't work. I have a button with 4 images. (1 in each state) I resize the image in state 1 and then click the paint brush. I then click on state 2 and when I mouse over the image on the slide my state 1 image actually appears. (If I do these steps in button edit mode then the state 1 images doesn't appear but it still doesn't resize the image)
