animation algorithm

I've got an algorithm that cycles through a tileset of a Mech
walking. It uses 3 variables: TimeCounter, AnimFrame, Footing.
TimeCounter is just an incrimental counter used for delay.
AnimFrame represents where in the tileset to get the source image.
Footing represents which step (ie: 0 = left foot first, 1 = right)

Code:

long TimeCounter, AnimFrame, Footing;

//in the main game loop
TimeCounter++;
if(TimeCounter==150000)
{
     if(AnimFrame==0) //center point, legs even
     {
         if(Footing==0)
         {
            AnimFrame=1;
         }
         else
         {
           AnimFrame=5;
         }
     }
     else if(AnimFrame>=1 && AnimFrame<=3)
     {
        if(Footing==0)
        {
          AnimFrame++;
        }
        else
        {
          AnimFrame--;
        }
     }
     else if(AnimFrame==4)
     {
       Footing=1;
       AnimFrame=3;
     }
     else if(AnimFrame==5)
     {
       if(Footing==0)
       {
         AnimFrame=0;
       }
       else
       {
         AnimFrame=6;
       }
     }
     else if(AnimFrame>=6 && AnimFrame <=7)
     {
        if(Footing==0)
        {
          AnimFrame--;
        }
        else
        {
          AnimFrame++;
        }
     }
     else if(AnimFrame==8)
     {
        Footing=0;
        AnimFrame=7;
      }
     TimeCounter=0;
}

This works fine for me, but I was wondering what any of you
guys thought. Any suggestions on how to optimize it?

I've attached the sprite tileset I used in testing it. Forgive the
artwork, it's pre-Alpha stage of a game I'm working on so it's not very detailed (ie: just basic textures, etc.).

By the way, to give you an idea of the speed of C++ vs. VB (and
I'm sure I'm not telling you somethin you don't already know),
this is an algorithm I had written in VB and the TimeCounter
check value was 30 there (here I had to set it to 150000,
because it would run TOO FAST otherwise)! Man, I love C++!!!

I don't see a link to the file I attached.
