Simple image resizer

This uses the GetImageSize function to get the size of the image you specify . The GetImageSize function returns an array with 4 elements . The elements we are interested in are elements 0 and 1 , these hold the width of the image in pixels for index 0 and index 1 holds the height of the image in pixels . We then simply divide this by 2 to get an image 50% of its original size .

Code :

<?php
//image resizer by myscripting
//get the size of the original
$size = GetImageSize("aspbanner1.gif");
//store the resized dimensions in a variable
$sizeh50 = $size[1]/2;
$sizew50 = $size[0]/2;
?>
Original Image :
<br>
<img src ="aspbanner1.gif">
<br>
Resized image :
<br>
<img src ="aspbanner1.gif" height="<?php echo $sizeh50; ?>" width ="<?php echo $sizew50;?>">
