cocos2dx windows 8 can't read image file

cocos2d-x C++
#1

I can run HelloWorld Project, but I add another image,then change
CCSprite::spriteWithFile(“HelloWorld.png”); to CCSprite::spriteWithFile(“LOGO2.png”);
but always return NULL.
I already put the file into Resources folder
What do I miss something to fix that?

#2

I finally know how to fix it.
The image file need add into project from asset folder, not resource folder.
