SDL_image/C++ OpenGL Program: IMG_Load() produces fuzzy images

I'm trying to load an image file and use it as a texture for a cube. I'm using SDL_image to do that.

I used this image because I've found it in various file formats (tga, tif, jpg, png, bmp)

The code :

SDL_Surface * texture;

//load an image to an SDL surface (i.e. a buffer)

texture = IMG_Load("/Users/Foo/Code/xcode/test/lena.bmp");

if(texture == NULL){
    printf("bad image\n");
    exit(1);
}

//create an OpenGL texture object 
glGenTextures(1, &textureObjOpenGLlogo);

//select the texture object you need
glBindTexture(GL_TEXTURE_2D, textureObjOpenGLlogo);

//define the parameters of that texture object
//how the texture should wrap in s direction
glTexParameteri(GL_TEXTURE_2D, GL_TEXTURE_WRAP_S, GL_REPEAT);
//how the texture should wrap in t direction
glTexParameteri(GL_TEXTURE_2D, GL_TEXTURE_WRAP_T, GL_REPEAT);
//how the texture lookup should be interpolated when the face is smaller than the texture
glTexParameteri(GL_TEXTURE_2D, GL_TEXTURE_MIN_FILTER, GL_LINEAR);
//how the texture lookup should be interpolated when the face is bigger than the texture
glTexParameteri(GL_TEXTURE_2D, GL_TEXTURE_MAG_FILTER, GL_LINEAR);

//send the texture image to the graphic card
glTexImage2D(GL_TEXTURE_2D, 0, GL_RGBA, texture->w, texture->h, 0, GL_RGB, GL_UNSIGNED_BYTE, texture-> pixels);

//clean the SDL surface
SDL_FreeSurface(texture);

The code compiles without errors or warnings !

I've tired all the files formats but this always produces that ugly result :

I'm using : SDL_image 1.2.9 & SDL 1.2.14 with XCode 3.2 under 10.6.2

Does anyone knows how to fix this ?

The reason the image is distorted is because it's not in the RGBA format that you've specified. Check the texture->format to find out the format it's in and select the appropriate GL_ constant that represents the format. (Or, transform it yourself to the format of your choice.)
