How to display image from an undisclosed folder using PHP?

You can easly display image using another PHP file.

You can pass image name after .php file.

Instead of linking directly to the image in your web page, the <img> tag links to the proxy script, and passes the name of the image as a query string.

Example:

<img src="proxy.php?img=profile.jpg" alt="This is drawn from a hidden folder" ... />

Enjoy!
