3 Image files to show the issue

There are 3 images in the attached ZIP:

"Image 1 - Original.tga"
"Image 2 - This is what it DOES look like.png"
"Image 3 - This is what it SHOULD look like.png"

If I use IMG_Load() to load the 1st image then when I display it using the new native SDL 1.3 API it looks like Image 2.  If I convert the image to a PNG (Image 3) and load it, it looks correct.

This may be a SDL_image issue and not an SDL 1.3 issue, but since it displays correctly if I use SDL-1.2.14 I am filing it as and SDL 1.3 issue.

Code snippet:

SDL_TextureID LoadImage( char *pFile, int& nW, int& nH )
{
    SDL_TextureID nID = 0;

    SDL_Surface *pSurface = IMG_Load( "Image 1 - Original.tga" );

    if ( NULL != pSurface )
    {
        nID = SDL_CreateTextureFromSurface( NULL, pSurface );

        // Save the width and height of the image
        nW = pSurface->w;
        nH = pSurface->h;

        SDL_FreeSurface( pSurface );
    }

    return nID;
}

void DrawImage( SDL_TextureID nSrcID, int nX, int nY, int nW, int nH )
{
    SDL_Rect dstRect;

    dstRect.x = nX;
    dstRect.y = nY;
    dstRect.w = nW;
    dstRect.h = nH;

    SDL_RenderCopy( nSrcID, NULL, &dstRect );
}
