Hello Lalit, I guess you mean to say clicking an image on a web page using Selenium Webdriver. So to click an image using selenium webdriver, you can try this piece of code: 
package clickImageProject;
import org.openqa.selenium.By; 
import org.openqa.selenium.WebDriver; 
import org.openqa.selenium.chrome.ChromeDriver;  
public class ClickImage{    
    public static void main(String[] args) {        
        String Url = "https://www.edureka.co/devops-certification-courses";    
        System.setProperty("webdriver.chrome.driver","C:\\chromedriver.exe");    
        WebDriver driver = new ChromeDriver();     
        driver.get(Url);    
        //click on the "Edureka" logo on the upper left portion 
   driver.findElement(By.Xpath("//i[@class='icon-logo edu-logo-style']")).click();    
   //verify that we are now back on Edureka's homepage 
   if (driver.getTitle().equals("Instructor-Led Online Training with 24X7 Lifetime Support | Edureka")) {      
            System.out.println("We are back at Edureka's homepage");    
        } else {  
            System.out.println("We are NOT on Edureka's homepage");    
        } 
    driver.close();  
    } 
}
Now, in the code above, I have used Xpath to get the image location, but you can also use CSS selector.
