I'm doing a web-application that must have web site articles editing feature (like a CMS). In my editor I want to use images uploaded to my web site through some files/images manager. This manager has to be similar to, say the Joomla! Media manager, where users of the back-end can upload files/images and get URLs to that files/images.

The question is: Is there any ready-to-use files/images manager that I can use in my GXT application? I really do not want to do it by myself.

Thank you.
