Texture Map shows all white in the cube not the pictures

Hi, everyone! I'm a newer to OpenGL. I need to paint BMP format pictures to a cube with texture map. I read as BMP format, and the texture map process was correct. I have use VS debugger and seems that the value were all right, however, the whole cube was all white. I have asked others to help me, they said that the process was right, but still couldn't found the resolution. Wish you can help me!
Thank for any help! Wish your reply soon!
Here is my code.

Code:

#include "stdafx.h"

GLuint textureid[6];
static GLfloat theta[] = {0.0,0.0,0.0};
static GLint axis = 2;

        BITMAPFILEHEADER header;    
        DWORD infosize;              // Size of header information
        DWORD bitsize;               // Size of bitmap
        GLubyte *bits;               // Bitmap pixel bits
        GLubyte *ptr;                // Pointer into bitmap 
        GLubyte temp;                // Temporary variable to swap red and blue
        int x, y;                    // X and Y position in image
        int length;               

        // Try opening the file; use "rb" mode to read this *binary* file.
        if ((fp = fopen(filename, "rb")) == NULL)
