I'm looking into the issue at the moment!
I can assure you the photos are still there. You can check by seeing
this.
When the server was hacked we lost some data and we probably lost the template file for the photo album. I'm looking into restoring it now.
This problem occurs with everything which makes use with the photoalbum. Thanks for pointing this out!
I'm going in to try and fix this now!
EDIT: I restored all the album related files and everything is working perfectly now! Sorry, for any trouble caused.
