Is it possible to add Video support into zenphoto version 1.1.4?

Sure, since it has been added to more current versions of Zenphoto. But why would you want to do that when you could just upgrade to the current version.

As you might expect, if you wish to do this with 1.1.4 you are on your own. We support only the current version.

Thanks for your reply. 1.1.4 is running fine on the website. So I thought it might be easier to add video support to that version instead of upgrading.
