The compiler never cares about checking existence of files, so it compiles fine does not mean the image's path is correct!

There is no such complicate things for show up images on buttons. It's pretty simple if you do it right. As Steve Luke pointed out, you need to check your image's path. Surely you did something wrong with it.
