安装MSI后无法在我的应用程序中显示png

我想知道msi安装的完整方法，因为 安装时创建的msi文件未显示.png类型的图片，为什么会发生这种情况以及如何解决此问题?

在创建msi之前，当我在vc ++ 2008中执行程序时，其显示图片.为什么在创建同一程序时无法查看png图片，为什么可以查看其他位图类型的图片.


我已将png图片放在res文件夹中.
并遵循以下步骤
解决方案资源管理器-> ResourceFiles->右键单击鼠标->添加现有项->(添加了res文件夹的png文件)

安装msi后，我还应该怎么做才能使png图片出现.
[更新]
我已使用图片ctrl显示png

I want to know the complete method of msi installation because The msi file created when installed is not displaying the pictures that are of .png type why does this happen and how to solve this problem?

Before creating msi when I execute the program in the vc++2008 its showing pictures. why I am not able to view png pictures when I create the same program msi other pics of bitmap type can be viewed.


I have placed png pictures in res folder.
and also followed the following procedure
solution explorer->ResourceFiles->right click mouse->add existing item->(added png files of res folder)

What else should I do to make my png pictures appear after installing msi.
[updated]
I have used picture ctrl to display png

BOOL CPictureCtrl::Load(BYTE* pData, size_t nSize)
{
	return LoadFromStream(pData, nSize);
}

....
CPictureCtrl m_picCtrl;
CFile picFile;
	if(picFile.Open(_T("res/uprightAcousticPiano.png"), CFile::modeReadWrite | CFile::typeBinary))
	{
		cout("opened");
		BYTE* pBuffer = new BYTE[(unsigned int)picFile.GetLength()];
		if(pBuffer != NULL)
		{
			picFile.Read(pBuffer, (UINT)picFile.GetLength());

			//Load the Image
			cout("displayed");
				m_picCtrl.Load(pBuffer, (size_t)picFile.GetLength());

			delete pBuffer;
		}
	}
