As i already posted in p.b.i some time ago, the tga header has the following
form (pascal/delphi syntax):

   T_TGA_header = packed record
    ID_size: Byte;            { ID-Field                   }
    Palette: Byte;            { 1= Palette exists          }
    Typ: Byte;                { Type (Mono, Color, compr.) }
    Pal_index: Word;         
    Pal_size: Word;          
    Pal_entry_size: Byte;    
    Lx    : Word;            
    Ly    : Word;            
    cX    : Word;             { Width                      }
    cY    : Word;             { Height                     }
    Bppix : Byte;             { Bits per Pixel - 1, 8, 24  }
    Image_des: Byte;          { Image Descriptor Flag      }
   end;

If Palette is 1 this if followed by a 3x256 byte palette of rgb triples. 
Otherwise only the raw data array is appended (RLE compression in some cases,
but that should not be neccessary here).
