I 've learned how to control the loaded image and I  got the concept of controlling Icon on the background.

PImage img;
int i;
int x;
int t;
int s;
int y;
int y1;
void setup()
{
 size(1000, 300);
 i=0;
s=100;
t=255;
y=20;
y1=20;
 img = loadImage("robot.jpg");
 frameRate(20);
}
void draw()
{
 background(255);

 //horizental
if ( (keyPressed == true) && ( (key =='a') || (key == 'A') ))
   i=i+20;

else if( (keyPressed == true) && ( (key =='b') || (key == 'B') ))
   i=i-20;

else if ( (keyPressed == true) && ( (key =='c') || (key == 'C') ))
  i+=y;
  if(i>900)
  {
    i=900;
    y=-y;
  }
 else if(i<0)
 {
   i=0;
   y=-y;
 }
 //virtical
 if ( (keyPressed == true) && ( (key =='d') || (key == 'D') ))
   x=x+20;

else if( (keyPressed == true) && ( (key =='e') || (key == 'E') ))
   x=x-20;

else if ( (keyPressed == true) && ( (key =='f') || (key == 'F') ))
    x+=y1;
  if(x>200)
  {
    x=200;
    y1=-y1;
  }
 else if(x<0)
 {
   x=0;
   y1=-y1;
 }
 

 //tint
 if( (keyPressed == true) && ( (key =='h') || (key == 'H') ))
   t=t-5;
 if( (keyPressed == true) && ( (key =='i') || (key == 'I') ))
   t=t+5;

if(t<0)t=0;
if(t>255) t=255;
tint(t);
 image(img,i, x,s,s);
