PNG can only be adjusted to a smaller size using IMG-Responsive, as opposed to scaling from small to large

I'm facing an issue when trying to adjust the size of a PNG image with a transparent background that has a width of 279 pixels and height of 432 pixels, using the img-responsive class in Bootstrap3.

The Issue:

Every time I attempt to upload the png image within the img tag with the class= "img-fluid", it remains the same size regardless of my scaling attempts. Other images seem to resize properly, but if I choose a larger image, it only scales from very large to normal size, rather than adjusting from normal to small.

My inquiry is

What is the most effective method for optimizing a PNG image for Bootstrap-3 with the class img-responsive?

HTML:

<div class="poster">
    <div class="container">
        <div class="intro-text">

            <div class="intro-heading">Welcome <img href="../html/indexfinal.html" class="bigv" src="../images/logos/bigvlogo.png" alt=""/> <img href="../html/indexfinal.html" class="midv" src="../images/logos/midvlogo.png" alt=""/> </div>
            <div class="intro-lead-in">Hi yall'</div>       

            <div class="container-fluid">

            <img class="mascot" src="../images/mascot/wave.png">

            </div>
             <a style="float:left" id="guestsignup"></a>

        </div>
    </div>
</div>

Answer №1

Yes, it will be effective.

<link href="https://maxcdn.bootstrapcdn.com/bootstrap/3.3.6/css/bootstrap.min.css" rel="stylesheet"/>
<div class="container">
  <div class="row">
    <div class="col-md-6">
      <img src="http://farm5.static.flickr.com/4017/4717107886_dcc1270a65_b.jpg" class="img-responsive" alt="Cinque Terre"> 
    </div>
  </div>
</div>

Try resizing the screen to observe the changes.

Answer №2

If you want to make the image responsive, simply include the img-responsive class in your existing code:

<img class="mascot img-responsive" src="http://farm5.static.flickr.com/4017/4717107886_dcc1270a65_b.jpg">

Hopefully this helps meet your needs!
