I want to show images in DOM when the guessed number is not 2? here's my code?

var dieRoll = Math.floor(Math.random() * 6) + 1;

prompt(' guess the number from 1 to 5 and if you guessed the right number you won or if you not you loose');

if (dieRoll === 2) { alert('you guessed it.... hurray'); document.write(' You are good in guessing ' + dieRoll); } else { alert('looser looser looser looser');

};

You'd probably benefit from the JavaScript and the DOM course, but here's one way you might do it:

yourpage.html 
  <!-- keep hidden until code reveals it -->
  <img id="reveal" style="display:none" src="loserpic.jpg">
yourscript.js 
//...
} else {
    alert('looser looser looser looser');
    document.getElementById("reveal").style.display = "";  // make image appear
};

Also, I notice that the entered value from the "prompt" isn't being used in the code, but the test for the value "2" is being done on a random number instead. Is that what you intended?

you could also to display from 0 to 6 this line of code: Math.floor(Math.random()*7);

you multiply by 7 you will still get the max answer 6 coz even 0.9999999 * by 7 will be 6.xxxxxx and with the Math.floor it always will down to the full number.
