<?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
$width = round($width * $percentage);
$height = round($height * $percentage);
//returns the new sizes in html image tag format...this is so you
can plug this function inside an image tag and just get the
return "width=\"$width\" height=\"$height\"";
}
?>
//Then in the HTML:
<?php
//get the image size of the picture and load it into an array
$mysock = getimagesize("images/sock001.jpg");
?>
<!-using a standard html image tag, where you would have the
width and height, insert your new imageResize() function with
the correct attributes -->
<img src="images/sock001.jpg" <?php imageResize($mysock[0],
$mysock[1], 150); ?>>
