Answer 1

在這種情況下，您必須調整您上傳的圖片的大小（200 * 150）和小（400 * 300）。這是用於jpg和jpeg圖像。

$filename = 'source.jpg'; 

// Get new sizes 
list($width, $height) = getimagesize($filename); 
$thumb_width = 200; 
$thumb_height = 150; 

$small_width = 400; 
$small_height = 300; 

// Load 
$thumb = imagecreatetruecolor($thumb_width, $thumb_height); 
$small = imagecreatetruecolor($small_width, $small_height); 

$source = imagecreatefromjpeg($filename); 

// Resize thumb 
imagecopyresized($thumb, $source, 0, 0, 0, 0, $thumb_width, $thumb_height, $width, $height); 

// Resize small 
imagecopyresized($small, $source, 0, 0, 0, 0, $small_width, $small_height, $width, $height); 

// Output thumb 
imagejpeg($thumb, "thumb.jpg"); 

// Output small 
imagejpeg($small, "small.jpg"); 

//save memory 
imagedestroy($thumb); 
imagedestroy($small);
