well I have drawn animated sprite which can move back and  forth across the bottom of the screen just above some grass sprites. here is my code.

#include <freeglut.h>
#include <iostream>
#include<SOIL.h>

using namespace std;

GLuint texture[8];

float screen = 0.0f;
float move_sprite = 0.0f;

void update(int value)
{
	screen += 0.125f;
	if (screen >= 0.875f)
	{
		screen = 0.0f;
	}
	glutPostRedisplay();
	glutTimerFunc(500, update, 0);
}

void drawSprite()
{
	glEnable(GL_TEXTURE_2D);
	glPushMatrix();
	glBindTexture(GL_TEXTURE_2D, texture[0]);
	glTranslatef(0.0f, -70.0f, 0.0f);
	glRotatef(90.0f, 0.0f, 0.0f, 1.0f);
	glBegin(GL_POLYGON);
	glTexCoord3f(0.0f + screen, 0.0f, 0.0f);

	glVertex3f(10.0f, -10.0f+ move_sprite, 0.0f);
	glTexCoord3f(0.125f + screen, 0.0f, 0.0f);

	glVertex3f(10.0f, 10.0f+ move_sprite, 0.0f);
	glTexCoord3f(0.125f + screen, 1.0f, 0.0f);

	glVertex3f(-10.0f, 10.0f+ move_sprite, 0.0f);
	glTexCoord3f(0.0f + screen, 1.0f, 0.0f);

	glVertex3f(-10.0f, -10.0f+ move_sprite, 0.0f);
	glEnd();
	glPopMatrix();
	glDisable(GL_TEXTURE_2D);
}

void drawBkgnd()
{
	glEnable(GL_TEXTURE_2D);
	glPushMatrix();
	glBindTexture(GL_TEXTURE_2D, texture[1]);
	glTranslatef(0.0f, -90.0f, 0.0f);
	glRotatef(90.0f, 0.0f, 0.0f, 1.0f);
	glBegin(GL_POLYGON);
	glTexCoord3f(0.0f, 0.0f, 0.0f);

	glVertex3f(10.0f, -50.0f, 0.0f);
	glTexCoord3f(1.0f, 0.0f, 0.0f);

	glVertex3f(10.0f, 50.0f, 0.0f);
	glTexCoord3f(1.0f, 1.0f, 0.0f);

	glVertex3f(-10.0f, 50.0f, 0.0f);
	glTexCoord3f(0.0f, 1.0f, 0.0f);

	glVertex3f(-10.0f, -50.0f, 0.0f);
	glEnd();
	glPopMatrix();
	glDisable(GL_TEXTURE_2D);
}
