how do i make my button's source image bigger without changing the button hover/clickable area?

Hey everyone, im trying to make a button's source image bigger but without making the clickable/hover area bigger, so if i made the source image bigger the button area is so much bigger and if i made the button area at the same size as the text the source image looks really small i've tried making the image bigger in photoshop but it never worked. thanks

everyone!
