title: Change Image's Background Color in HTML or CSS
body: <p>I just downloaded an html template, in that I can see the images having white background, but when those are used in site, they have background color changed. </p>
  
  <p><img src="https://i.stack.imgur.com/DQYpI.jpg" alt="Original Image"></p>
  
  <p>And this is what I see in the site:</p>
  
  <p><img src="https://i.stack.imgur.com/yaNOs.jpg" alt="Image in the site"></p>
  
  <p>So How to achieve this effect, I spent whole night changing background color of an image in photoshop, that does not look as good as it is in this image, </p>
  
  <p>So there must be some method in CSS to do this..?</p>
