Copy this code and paste it in your HTML
<?php function imageResize($width, $height, $target) { //takes the larger size of the width and height and applies the formula accordingly...this is so this script will work dynamically with any size image if ($width > $height) { $percentage = ($target / $width); } else { $percentage = ($target / $height); } //gets the new value and applies the percentage, then rounds the value //returns the new sizes in html image tag format...this is so you can plug this function inside an image tag and just get the return "width=\"$width\" height=\"$height\""; } ?> //Then in the HTML: <?php //get the image size of the picture and load it into an array ?> <!-using a standard html image tag, where you would have the width and height, insert your new imageResize() function with the correct attributes --> <img src="images/sock001.jpg" <?php imageResize($mysock[0], $mysock[1], 150); ?>>
