Users can inject XSS into the form field "Name", when adding a comment on a
picture. This will lead to the execution of XSS code.
Simple scripting like <script>alert('hello')</script> , and more advanced
document.location, and document.cookie works.
This has been tested on version 0.5.1. Other versions might be flawed too.
