Description: 
A mood board is a type of collage consisting of images, text, and samples of objects in a composition. They may be 
physical or digital, and can be "extremely effective" presentation tools.


Vulnerability:
wowproxy.php doesn’t require any authentication to the proxy images function.   Users can be misled to a malicious link
via this feature.

26 // Get the url of the image to be proxied
27 $url = ( isset( $_POST[ 'url' ] ) ) ? $_POST[ 'url' ] : ( isset( $_GET[ 'url    ' ] ) ? $_GET[ 'url' ] : false );

39 function proxyimages( $url )
40 {
41         header( "Location: ".$url );
42         exit;
43 }
