I want to display them on the same page without saving. And I need to do that in PHP. Is it possible? Please help! Note: If that is not possible,I can put them in some folder.

推荐答案

那么你必须制作第二个 PHP 文件.您必须在第一个文件 <img src='image.php'/> 中制作图像标记，并且在此 image.php 中您必须打印出图像，例如:

You have to make a second PHP-file then. You have to make an image tag in the first file <img src='image.php' /> and in this image.php you have to print out the image like:

header("Content-type: image/png");

$im     = imagecreatefrompng("image.png");
list($width, $height) = getimagesize($im);
$newimage = imagecreatetruecolor($new_width, $new_height);
imagecopyresampled($newimage, $im, 0, 0, 0, 0, "100", "100", $width, $height);

imagepng($newimage);
imagedestroy($newimage);
imagedestroy($im);
