Why wont this work?

I can't get my custom .blp icon for a spell i'm making to work. I've imported it and left it as war3importedfile/HyperBeam.blp yet it wont hsow up in game when I select it. can some one help me?

There is a problem with the worldeditor that when you import an image you need to save before you can select the image anywhere. Also if its replaceing a skin you need to change its path to the same as the one your replaceing.
