The requirement is to have either front end plug-in or back end processor that generates the preview of contents (such as images, videos, PDF files, HTML pages) in a preview popup when user mouse hovers the content.

I did some research on this, seems that there are assorted jquery plugins for each type of files, but what we are looking for is a framework that handles all types of file previews. Ideally, we want to generate preview images on the backend, considering the cost of retrieving content on front end.

I did find some open source or proprietary CMS that provides this feature, but usually they are shipped as one suite and the API for file preview might not be open.

Is there any java or jquery framework that handles file preview?

Thanks a lot
