Assuming you are working in 8 bit graphics modes, you should just have to do
this:

PALETTE pal;
BITMAP *bmp = load_bitmap("filename.here", pal);

bmp will contain your picture and pal will contain it's palette. Paint, the
Windows pain editor, saved for me a 136 byte file. A palette, unless compressed
(which I doubt) needs to be at least 768 bytes (RBG * 256 plus any header or
spacer).

Also for rotate_sprite, the angle is done using fixed notation.

Example (requires floating point math):

fixed degrees(float angle)
{
    return ftofix(angle/360.0*256.0); // float to fix conveter
}

// 25 degrees
rotate_sprite(screen, bmp, x, y, degrees(25));

Hope this helps.
