If your template already have these codes (it is usually situated above </head>
), simply change the value of (img_thumb) to 75 or according to your taste.
img_thumb_height = 75;
img_thumb_width = 75;
But if your template doesn’t include these codes, copy and paste it, just above the </head>
and you are ready to go. As you can see in the picture(before and after images), look at the difference. Which is better? Resizing the image in blogger homepage is always better.
