PHP从url地址生成图像

Question

Is the following situation possible and how:

A user goes to an internet address: www.example.com/image/123.png

File 123.png does not exist - it is created at the moment of entering the address and outputed to the user via imagepng.

Currently I am doing it like www.example.com/image/?link=123.png

I do not have shell access to the server.

If your hosting is using Apache, you can create a file called ".htaccess" in your document root (most often your "public_html" or "www" directory) with something like this (untested):

RewriteEngine on
RewriteCond %{REQUEST_FILENAME} !-f
RewriteCond %{REQUEST_FILENAME} !-d
RewriteRule ^image/(.*)$ image/?link=$1

This is Apache's mod_rewrite functionality.
