将 RewriteEngine 模式打开

URL rewriting + PHP code correction, write URL rewriting rules

<IfModule mod_rewrite.c>
    RewriteEngine On
    # 将 host/img/下的链接全部处理
    RewriteCond %{REQUEST_FILENAME} !-d
    RewriteCond %{REQUEST_FILENAME} !-f
    RewriteRule ^(.*+)$ img/index.php?img= [L]
</IfModule>

Use PHP code to process images

<?php
    // do something...
    echo file($_GET['img']);

If you’re not serious, you can also add your own website’s watermark to the picture

At LZ’s request, the following demo:

<?php
if (isset($_GET['img'])) {
     header("Content-type: image/png");
     $im=imagecreatefrompng($_GET['img']);
     $text_color = imagecolorallocate($im, 255, 0, 0);
     imagestring($im, 16, imagesx($im)-16*13, imagesy($im)-16,  "from atd3.cn", $text_color);
     imagepng($im);
     imagedestroy($im);
 } else {
    echo 'No Image';
}

Original image

Insert URL and watermark
