Image Resizing with PHP

Hello guys,

Today I will post a image resizing script, this will assist you in all of your sites specially ecommerce ones in which you need to display your products with different sizes. The script is self explanatory, but please send me a message or a comment if you need further assistance with it.

//Image Target

$pic = ???images/???.$_GET[‘pic’];

//Set Max Sizes

$max_height = 48;

$max_width = 48;

//Get Image Size

$size= getimagesize($pic);

//Set Ratios

$width_ratioξ = ($size[0] / $max_width);

$height_ratio = ($size[1] / $max_height);

if($width_ratio >=$height_ratio)

{

$ratio = $width_ratio;

}

else

{

$ratio = $height_ratio;

}

//Set new size

$new_widthξξξ = ($size[0] / $ratio);

$new_heightξξ = ($size[1] / $ratio);

//Set header

header(???Content-Type: image/jpeg???);

//Create Image

$src_img = imagecreatefromjpeg($pic);

$thumb = imagecreatetruecolor($new_width,$new_height);

imagecopyresampled($thumb, $src_img, 0,0,0,0,$new_width,$new_height,$size[0],$size[1]);

imagejpeg($thumb);

imagedestroy($src_img);

imagedestroy($thumb);

All you need to do now is to point the src element of your image tag to this script, and set the file you desire using the get method. Ex: img.php?pic=image.jpg

Please contact me with any doubts,
